Slice imaging of methyl bromide photofragmentation at 193 nm
The photodissociation of methyl bromide at 193 nm is studied using slice imaging. From the measured photofragment translational energy and angular distributions we were able to extract methyl-state-specific dissociation channel yields and crossing probabilities between 3Q0 and 1Q1 surfaces. The angular distributions for the Bromine photofragments show a strong dependence on the total translational energy release. Nonadiabatic transition probabilities from the 3Q0 to 1Q1 surface dominate the dynamics in this excitation energy region and for most of the methyl vibrational states probed.
