Abstract
Comparative data of the experimental and quantum-chemical investigatio ns of the photochromic anils and model compounds lead to the conclusio n about unusual ''twisted'' cis (with regard to C-N-bond) zwitterion N +H-structure of photocolored form with nearly orthogonal Ar-C- and CH- NH+-groups. This form is stabilized kinetically by the intermolecular interactions in the rigid media and crystals.
