英文摘要: The photodissociation of o-bromotoluene at 266 nm has been investigated using the universal crossed laser-molecular beam technique. The angle-resolved time-of-flight (TOF) spectra corresponding to Br photofragment are measured at different lab angles. The observed translational energy distribution and anisotropy parameters of the Br photofragment indicate that o-bromotoluene dissociates via two channels. In the first channel, the anisotropy parameter beta is determined to be 0.5 +/- 0.2 and the average translational energy is only 9% of the available energy. In the other photofragmentation channel, beta is determined to be - 0.4 +/- 0.2 and 44% of the available energy is assigned to translational energy. Possible mechanisms are discussed.
