Abstract
Photodissociation dynamics of benzene under 193 nm and 157 nm photon excita tion have been studied using the molecular beam photofragmentation spectros copic technique. By detecting the H atom products produced away from the ph otolysis region, the lifetime of the excited benzene molecule as well as th e kinetic energy distribution of the H atom elimination process can be dete rmined simultaneously. Experimental results show that the H atom eliminatio n from benzene occurs on the ground electronic state in which the excess en ergy is likely fully randomized.
