Fulfilled requests Oct 2006 through Jan 2007 at Wikipedia:WikiProject_Chemistry/Image_Request/Archive01.

This is a subpage for image requests on WikiProject Chemistry.

The aim here is to make bring existing articles alive by the use of interesting images. This can be accomplished by:

photographs of samples of chemicals to give readers an idea of what they are beyond a one-dimensional text
photographs of reaction set-ups to see what chemists do
spectacular chemical reactions or similar, such as those shown on Flame test and atomic carbon
adding illustrative 2D or 3D line images to articles
Please place all images on the Commons, so other language wikipedias can benefit from your hard work.
Feel free to add to this list! Also, feel free to jump in and help out!

Methylene - chemical structure for different species? -- Quantockgoblin 14:24, 15 November 2006 (UTC)
Methylation - reaction schematic -- Quantockgoblin 14:24, 15 November 2006 (UTC)

I added in the scheme from iodomethane, with a little explanation. Maybe you also want a schematic of a biochemical methylation, too? That's out of my field...Walkerma 16:30, 20 March 2007 (UTC)

Copper aspirinate - space filling model of crystalline state, maybe? I'll take care of the reaction mechanisms Bfesser 03:28, 25 February 2007 (UTC)
Resonance structures for thiophene, pyrrole and furan -- Quantockgoblin 14:56, 4 March 2007 (UTC)
A picture of ethylene with internal coordinates marked. --HappyCamper 01:38, 2 April 2007 (UTC)

[edit] Chemical photographs

Have a look at Category:Chemistry pages needing pictures; pages transcluding {{chembox new}}, {{drugbox}}, {{protein}}, or {{chemical drawing needed}} automagically categorise all chemical compounds which do not have a picture in their infobox into this category.

Picture of a grignard reagent. --HappyCamper 21:18, 6 November 2006 (UTC)
Photo of a stable carbene. This is a bit of a wild request, but if people are still in the habit of subliming stable carbenes, perhaps they could take a photo and upload it. A nice way to sublime these carbenes (when free from metals) is to place a tight fitting rubber filtration cone (the sort used for getting a good seal when using a Buchner funnel) half way up the outside of a schlenk tube and fill it with dry-ice acetone and gently heat the crude solid carbene in the bottom of the schlenk tube with warm water whilst applying a vacuum. The carbene sublimes as a nice white band, perfect for a photo. I would do it myself, but I'm no longer in the lab. Quantockgoblin 18:00, 14 November 2006 (UTC)
Buckminsterfullerene in benzene. --HappyCamper 18:08, 14 November 2006 (UTC)
I would like to request for the Wikipedia:Chemistry Collaboration of the Month article solubility some images relevant to this page, obvious things as solids being dissolved or an image of two immiscible liquids on top of each other. I lack a laboratory and a camera! so help much appreciated.... V8rik 20:20, 22 January 2007 (UTC)
Diagram of interesterification showing linolenic acid being replaced by stearic acid at the sn2 position in a triglyceride. David.Throop 21:50, 22 January 2007 (UTC)
A nice picture for {{chemical drawing needed}} (I would like to use this template outside the infoboxes to request images on chemistry pages where a picture would e.g. improve the explanation or replace wrong images with this template). Feel free to make something beautiful! --Dirk Beetstra ^{T C} 15:23, 4 March 2007 (UTC)

Dirk, I've suggest a possible type of image to use for this template - see http://en.wikipedia.org/wiki/Template_talk:Chemical_drawing_needed -- Quantockgoblin 16:57, 4 March 2007 (UTC)

I have seen it, let's discuss it there. --Dirk Beetstra ^{T C} 17:08, 4 March 2007 (UTC)

double oblique stopcock; a photo of one of these please - i.e. the type of tap used in a vacuum-gas manifold (i.e. a glass tap with 2 separate parallel 'channels/lines' that run diagonal to the axis of the tap). -- Quantockgoblin 00:05, 13 February 2007 (UTC)

[edit] Miscellaneous

Pictures relevant for surface chemistry. --HappyCamper 16:02, 13 November 2006 (UTC)
Photoelectron spectra. --HappyCamper 16:02, 13 November 2006 (UTC)
E. J. Corey. I have been unable to find a photo of EJ with the appropriate copyright. Maybe you'll have more luck. ~K 16:25, 29 November 2006 (UTC)
Wanting to make a infobox for chemistry topics which looks similar to the Cuisine feel of infobox; would require a picture or diagram of something which personifies chemistry in both practical and theoretical instances. So, something like a beaker, Erlenmeyer flask, chemical formulae or notable chemist, just give a little more "oomph" to the wikipedia chemistry articles. JCraw 13:22, 27 November 2006 (UTC)
- Suggestions:
  - A mini table of elements? Maybe does not have enough "oomph", but would at least be instantly recognizable? -- Quantockgoblin 16:47, 27 November 2006 (UTC)
  - Just to illustrate the idea, e.g.:

- or -

, the text can be changed - what dimensions do you need? --Quantockgoblin 18:46, 28 November 2006 (UTC)

- - Another option might be to use chemical hazards in some way e.g.

Quantockgoblin 21:48, 28 November 2006 (UTC)

I prefer the periodic table. Emphasizing the hazards of chemistry sends a bad message, in my opinion. --Ed (Edgar181) 13:25, 29 November 2006 (UTC)

Ed, I think you are right - I was looking for something with a bit more colour/oomph - (more arrrghh than oomph it would seem!!) --Quantockgoblin 13:54, 29 November 2006 (UTC)

What if we made a collage of materials? --HappyCamper 14:46, 8 December 2006 (UTC)

or maybe a bit chemistry apparatus "as seen on TV" e.g. (although I would need all the bits to be in the wrong order and some dry ice in there somewhere too!!):

- just as a sort of idea, can be fancied up a bit?

- I don't have the skills to do this well but it's an idea that could be used?!

[edit] UV Spectra

I'm editing Leukotriene. [1] says

The triene designation refers to the signature ultraviolet spectrum due to three conjugated double bonds. The subscript denotes the total number of double bonds - four when derived from arachidonate.

Could anybody supply that UV spectra?
David.Throop 17:03, 15 January 2007 (UTC)

[edit] Unclear/incorrect images

(list pages where people commented on correctness of the image(s), or where image is apparently unclear. See talk page of the page for more information)

[edit] Editors willing to take image requests

Quantockgoblin - I'll consider requests relating to drawing chemistry lab equipment/techniques.
Ben Mills - I'm always happy to create 3D models (ball-and-stick, space-filling, polyhedral) and I do skeletal formulae and reaction mechanisms too, although not in SVG yet.
Fvasconcellos—glad to take on requests of skeletal formulae in SVG format and high-resolution 3D models in PNG format.
Edgar181 (talk • contribs) - 2D & 3D models, reaction mechanisms, lab photos, whatever. Just drop a note on my talk page.

[edit] Fulfilled requests/repaired images

(move them here after they've been done)

Drying tube Rifleman 82 19:16, 31 October 2006 (UTC)

Got an image of a couple types. I don't have anything to pack them with right now, but I'll try to grab another picture of one when I do.

Bfesser 03:49, 25 February 2007 (UTC)

That's great! Thanks! --Rifleman 82 06:03, 25 February 2007 (UTC)

Buprenorphine

Done.

--Ed (Edgar181) 19:03, 1 February 2007 (UTC)

Images for these please (with numbering):

benzotriazole
Pyrrolidinones

-- Quantockgoblin 11:51, 26 January 2007 (UTC)

Done:

--Ed (Edgar181) 16:41, 2 February 2007 (UTC)

For alkane article, please can 2-methyl-butane, with the numbering (1-4) put on the butane chain, thanks -- Quantockgoblin 07:45, 6 February 2007 (UTC)

Voilà:

. Ben 10:44, 6 February 2007 (UTC)

thanks -- Quantockgoblin 14:06, 6 February 2007 (UTC)

I believe these need some sterochemisty:

Methadone

-- Quantockgoblin 18:25, 29 January 2007 (UTC) thanks

Methadone seems to be used as a racemate - the CAS number in the article is for (+/-)-methadone. --Ed (Edgar181) 19:03, 1 February 2007 (UTC)

Leukotriene has an incorrect diagram for LTB4; correct conformation shown at PubChem David.Throop 07:08, 11 February 2007 (UTC)
- Fixed, now it should be ok: Image:Leukotriene B4.svg, also Image:Leukotriene E4.svg be. --Calvero JP 09:53, 11 February 2007 (UTC)

Hirsch funnel Rifleman 82 23:00, 31 October 2006 (UTC) -- Not the best photo, but the job appears to be done.
Vigreux column Rifleman 82 19:52, 3 November 2006 (UTC) -- job appears to have been done -- Quantockgoblin 10:23, 12 February 2007 (UTC)

For alkane article please can I have the all possible C₄-alkane isomers (i.e. n-butane, isobutane, cyclobutane and methylcyclopropane as a composite image. Also do anyone think it is reasonable to include the cyclobutane with a bridging carbon-carbon bond (i.e. like two triangles back to back) - does it even exist as an intermediate? Currently there is an incomplete list of all possible C₅-isomers on the alkane page. I'd like to replace that image with the one requested. Also, we are typing to make alkane a featured article, it would be great if you can make the iamge nice on the eye. -- Quantockgoblin 00:40, 6 February 2007 (UTC)

Possible isomers of C₄-alkanes (left to right): n-butane and isobutane are isomeric (C₄H₁₀); methylcyclopropane and cyclobutane are isomeric (C₄H₈); isocyclobutane (C₄H₆) has no alkane isomers

- done (at low-ish resolution) - I'm sure someone can do it at higher and with svg?

Do you mean SVG for the skeletal formulae or the ball-and-stick models? The latter usually look better as hi-res PNG. Fvasconcellos 17:21, 11 February 2007 (UTC)

Actually before you kindly do anything, I've just thought, are cyclic alkanes strictly isomer of straight chain alkanes e.g. hexane C6H14 and cyclohexane C6H12 have different chemical formula! If they are not isomers (which now I suspect) then maybe I don't need the image as it is factually incorrect. The 'isomers' I have drawn are just C4-analogs!?! --Quantockgoblin 21:45, 11 February 2007 (UTC)

Cycloalkanes are isomeric with alkenes - they have the general formula C_nH_2n. What you want are all the possible isomers with formula C₄H₁₀.Ben 21:48, 11 February 2007 (UTC)

Well that's only butane and isobutane unless I'm very mistaken. Fvasconcellos 22:08, 11 February 2007 (UTC)

Correct! -- Ben 22:10, 11 February 2007 (UTC)

LOL. Thank you for validating—do we need a reference for that? :D Fvasconcellos 22:13, 11 February 2007 (UTC)

Ok, I've decide that I can still use the image as shown right with a correct lable. So with reference to Fvasconcellos original question, ball and stick please! -- Quantockgoblin 08:10, 12 February 2007 (UTC)

~~Will do.~~ Done—how's this to the left? Is the file too big, and is the filename OK? I couldn't think of what to call it :) Fvasconcellos 12:27, 12 February 2007 (UTC)

Looks very good to me - already replaced old image on alkanes page, thanks! -- Quantockgoblin 23:51, 12 February 2007 (UTC)

The section Benzopyrene#Interaction with DNA just got a {{confusing}}, and I can see why, the text is heavily invested with chemical formulae, which makes the section unreadable for many people. I think that an reaction scheme (and a rewrite of that section) would clarify a lot, there (I can help with the rewrite, if you want). --Dirk Beetstra ^{T C} 10:57, 17 December 2006 (UTC)

Done by User:Jrockley

Could someone please replace Image:Con polymer.png with a version that has licensing and source information? I would tag it with {{subst:nld}} and {{subst:nsd}}, but I doubt whether this image can be deleted (due to technical concerns). Thanks.

1,2,4-trichlorobenzene, please -- Quantockgoblin 11:31, 23 February 2007 (UTC)
- I created images for the three isomers of trichlorobenzene:--Ed (Edgar181) 13:04, 23 February 2007 (UTC)
  - Thanks, you're getting faster! - Quantockgoblin 13:25, 23 February 2007 (UTC)
Some simple ring systems without numbering (can we number these please):

-- thanks Quantockgoblin 11:54, 26 January 2007 (UTC)

Here we go:

--Ed (Edgar181) 15:53, 21 February 2007 (UTC)

Well done! -- Quantockgoblin 20:43, 27 February 2007 (UTC)

Would anybody be willing to turn a PowerPoint slide into a SVG? This is for Eicosanoid#Mechanisms of ω-3 eicosanoid action. David.Throop 16:13, 29 January 2007 (UTC)

Done - thanks David.Throop 15:27, 4 March 2007 (UTC)

reaction scheme on Methylcyclopentadienyl manganese tricarbonyl contains "Et2Al6" i.s.o "Al2Et6". See talk:Methylcyclopentadienyl manganese tricarbonyl. --Dirk Beetstra ^{T C} 13:52, 12 January 2007 (UTC)
