摘要：

Triplet formation of aromatic hydrocarbon solute in aliphatic hydrocarbon solution in the picosecond to a few nanosecond time region induced by multiphoton excitation with 266-nm picosecond laser pulse is demonstrated. Mechanisms of the rapid triplet state formation, especially the contribution of the ionized state of solvent molecule to it, are discussed by comparing the results of picosecond laser photolysis studies with those of pulse radiolysis studies on nonpolar solutions of aromatic hydrocarbons, where a rapid solute triplet formation in the subnanosecond region has been observed rather frequently. © 1990 American Chemical Society.
