英文摘要	the photodissociation of m-bromotoluene at 266 nm has been investigated on the universal crossed molecular beam machine, and the time-of-flight (tof) spectra of recoiling photofragment at different angles were measured with the photofragment translational spectroscopy (pts) detecting technique. the observed tof spectra indicate that there are two different dissociation channels, one is channel (a) beta = 0.7 +/- 0.1 and (e-t) = 3.76 +/- 0.5 kcal/mol, the other is channel (b) beta = 0.2 +/- 0.15 and (e-t) = 12.13 +/- 0.5 kcal/mol. to better interpret the experimental results and primary photodissociation mechanism, the ultraviolet-visible (uv) absorption spectra of m-, o- and p-bromotoluene were measured, and the geometries of m-bromotoluene were optimized at the casscf(8,7)/6-311g(**) level. two probable photodissociation mechanisms are suggested based upon the experimental results and the ab initio calculation.
