Photosensitized Reactions of Psoralen and Herbicides Revealed by the Pump-Probe Method

Abstract:

Formation of triplet states in aqueous herbicide solutions excited by nanosecond radiation of 4^th harmonic of Nd:YAG laser (wavelength 266 nm) is revealed by the pump-probe method. During photosensitized 8-MOP oxidation of herbicides, formation of triplet states of the photosensitizer and of the hydrated electron is observed in the process of two-step photoionization of 8-MOP.
