A closer look at photochemical reactions of transition-metal compounds by time-resolved EPR

A review is given of applications of time-resolved Electron Paramagnetic Resonance (TREPR) in the field of photochemistry of transition metal compounds. The two main TREPR techniques used in these studies are described. A brief overview is given of Chemically Induced Dynamic Electron Polarization (CIDEP) mechanisms that can affect TREPR spectra and that can give insights into the mechanism of photochemical reactions. Following these background sections experimental results are presented. The discussion focuses in particular on the Fourier Transform EPR (FT-EPR) studies of photoinduced metal–alkyl bond homolysis reactions of a series of transition metal (Co, Ru, Re, Pt) complexes carried out by the authors.Fil: Martino, Debora Marcela.
