Talk:Diatomic molecule

From Wikipedia, the free encyclopedia

is sulfur, selenium, or tellurium a diatomic molecule in the atmosphere

If atoms in a diatomic molecule are not chemically bonded, what is the link between them?

S, Se, & Te don't (at least normaly) form diatomic molecules. S in the atmosphere is as SO2, SO3, H2S, or sulfate aerosols. And diatomic molecules are held together with single, double or triple covalent bonds. -Vsmith 15:53, 20 Apr 2005 (UTC)

[edit] Mono, di, tri, tetra, penta, hexa, hepta and octatomic elements and molecules

I was wondering if we should combine these in some way, as some of the articles are probably going to be pretty short. Each of them has at least two meanings. For example, a "tetratomic molecule" is one with four atoms and a "tetratomic element" is an element that forms a molecule with four atoms of that element. If they are combined, what should the article be named? "Mono and polyatomic elements and molecules"? -- Kjkolb 11:21, 26 November 2005 (UTC)

Please could we have a derivation for the ratio of specific heats for a diatomic ideal gas?

[edit] Nonsense: Comparison between rotation and vibration

"The lowest rotational energy level is when l = 0."

Um, OK.

Erot,0 = l*(l+1)*hbar**2 / (2*I) = 0 * (0+1) hbar**2 / (2*I) = 0

Not sure how that one got screwed up.

[edit] Harmonic oscillator?

Erm.

"exactly the same as a harmonic oscillator" - no, it isn't. The vibration of a diatomic molecule is anharmonic and more closely follows the Morse potential than the parabolic well. The article on the morse potential actually links to this one.
