Summary:The photodissociation of n-C 5H 11Br at 234 nm has been investigated utilizing the ion velocity imaging technique. The two-dimensional images provide detailed information on the translational energy distributions and anisotropy parameters. The obtained translational energy distributions corresponding to the Br and Br ∗ fragments have been fitted by a single Gaussian function, respectively. The anisotropies for the Br and Br ∗ channels are measured to be β = 1.08 and 1.84, respectively. The contributions of each electronic state have been estimated and the probability of nonadiabatic transition between 3Q 0 and 1Q 1 states is determined to be 0.47.
