Add time:08/21/2019 Source:sciencedirect.com
The photodissociation of CH2BrCH2Cl at 266 nm has been investigated on the universal crossed molecular beam machine. The primary dissociation step leads exclusively to the formation of CH2CH2Cl radicals and Br atoms in the electronic ground state as well as in the spin–orbit excited state, with a branching ratio 2±1:8±1. Photofragment total c.m. translational energy distribution P(Et) has been obtained and about 64% of the available energy is partitioned into translational energy for Br channel and about 28.5% of the available energy is partitioned into translational energy for Br∗ channel. The anisotropy parameters are determined to be β(Br∗)=0.8±0.2 and β(Br)=−0.6±0.2, respectively. Some CH2CH2Cl radicals with large internal excitation (corresponding to formation of ground state Br channel) may undergo secondary dissociation to form CH2CH2+Cl. The experimental results are discussed in terms of a model that involves the initial excitation of two repulsive electronic states: one from an parallel transition to the 3Q0 state, and the other from a perpendicular transition to the 3Q1, 1Q states.
