Research on Photochromic and Photochemical Reaction Mechanisms.

Abstract

The direct observation by nuclear magnetic resonance (NMR) of a number of photochemical systems is reported. By NMR, the primary photochemical transformations in anils having a hydroxyl group ortho to the exocyclic -CH= were confirmed. N-salicylidene mitroanilines were studied. Spiropyrans appear to form stable free radicals with long-term irradiation. Exact analysis of complex NMR specta could yield new and important photochemical information. The exact analysis of the 7-spin ABB'CC'DX system of the 13C-H satellities of benzene was carried out. All NMR spectral parameters for benzene were obtained simultaneously for the first time; no simplifying assumptions or isotopically labeled compounds were used. (Author)
