Abstract:

Time-resolved electron spin resonance (TR-ESR) is a powerful technique which can be used to detect and identify short-lived intermediates in photo-induced reaction. The chemically induced dynamic electron polarization (CIDEP) signal measured by the TR-ESR technique can provide rich information on the mechanism and dynamics of photochemical reaction. In this review,  the four CIDEP mechanisms and the home-made TR-ESR with balance reflection bridge-type circuit and zero difference beat balance mixing frequency model are introduced. The applications of TR-ESR in investigation on laser photolyzed radicals are summarized.

Key words: TR-ESR,  CIDEP,  photolyzed radicals
