Popis:	A variety of N-(dialkylaminomethyl)benzotriazoles are shown by 1H and 13C n.m.r., i.r., and X-ray crystallography to exist solely in the 1-substituted form in the crystalline phase, but as an equilibrium mixture of the 1- and 2-isomers in the liquid, melt, solution and argon matrix phases. The 1- and 2-isomers equilibrate by an intermolecular mechanism as proven by cross-over experiments.
