Abstract

Modern NMR-based methods of studying the kinetics and mechanisms of reversible photochemical reactions in solutions are discussed. Modern NMR methods based on the lineshape analysis, double resonance spin saturation transfer, and inverse fractional nuclear spin population transfer are applicable to studies of the kinetics and mechanisms of reversible photochemical processes in solutions characterized by the effective rate constants for the photoprocesses. They offer unique possibilities for studying the kinetics of photoinduced chemical exchange processes immediately under hotostationary conditions and analyzing the interconversions of molecular forms in degenerate systems. The Forsen Hoffmann double resonance NMR (or spin saturation transfer technique) can be used for studying the kinetics of reversible dark chemical reactions. The analysis of the time-dependent NMR lineshape can be used for predicting the kinetics of photoinduced chemical exchange under nonstationary conditions.
