[edit] Tautomers or Resonance forms ?
Does anybody know whether the s-triazinetriol and s-triazinetrione forms are tautomers or resonance forms? H Padleckas 01:25, 7 May 2005 (UTC)
These are indeed tautomers, since atoms cannot be moved when going between resonance forms, and you will note that the Hs have moved. There are several "mixed" tautomers possible too. I recall doing a Chem Abstracts search through the 1930s literature for a compound like this and finding about 3 or 4 of these tautomers all listed independently- a nightmare!
