Abstract

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.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
