Abstract

Abstract: Aromatic cation radicals ArH" are spontaneously produced as solvent-caged species together with anions and radicals by the irradiation of the charge-transfer absorption band of the electron donor-acceptor complex [ArH, TNM], where ArH and TNM represent a series of anisole donors and the tetranitromethane acceptor, respectively. The subsequent fate of the geminate species [ArH", C (N02) 3-r NOz'](111) depends strongly on the solvent ...
