Abstract：In the present paper the photo-ionization and properties of excited state of benzoic acid and its methyl substitutes were studied using 248 nm laser flash photolysis. The quantum yields of hydrated electrons produced from photo-ionization, the life-time of excited triplet, and the self quenching rate constants were also determined. It is shown that there isn’t significant effect of different position of methyl residue at benzene ring on its excited triplet. The resonant excitation of triplet of benzoic acid was explored by the use of two-steps laser flash photolysis. The possible upper excited state and radical involved in the processes were guessed.
