Dynamic and stimulated nuclear polarisation in photochemical radical reactions

Abstract

Highly sensitive time-resolved magnetic resonance techniques based on the effect of variable radio-frequency and switched constant magnetic fields on the nuclear polarisation of diamagnetic products of radical reactions are considered. The applications of these methods to the investigation of short-lived radical intermediates (radical pairs, biradicals, free radicals and radical ions) formed in photochemical reactions in homogeneous and molecular-organised media are discussed. The bibliography includes 148 references.
