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 ABBCCDX 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
