Abstract
The photodissociation of n-C4H9Br at 232-267 nm has been investigated utilizing velocity map ion imaging. The two-dimensional images provide detailed information on the translational energy distributions and anisotropy parameters of the photoproducts (Br and Br*). The experimental data and our ab initio calculations indicate that the photodissociation in the investigated range originates from the three low-lying dissociative electronic states, as assigned as 1A″, 2A′ and 3A′ in Cs symmetry. Then, the origins of the photofragments (Br and Br*) are assigned to the individual pathways. The dissociation energy of the C-Br bond of n-C4H9Br is determined to be D0 = 333.4 ± 1.5 kJ/mol.
