Crossed-beam and reduced dimensionality studies of the state-to-state integral cross sections of the Cl + HCD3(v) → HCl(v′) + CD3 reaction

The state-to-state integral cross sections of the Cl + HCD3(v) → HCl(v′) + CD3 reaction have been studied experimentally and theoretically. Reactions involving both Cl ( 2 P 3 / 2 ) and Cl ( 2 P 1 / 2 ) were analysed. In the experiment, a time-sliced velocity imaging detection method under crossed-beam condition was used. For theoretical study, a multiple potential energy surface model is employed. A combined reduced dimensionality quantum dynamics and quantum chemistry method is used with explicit treatment of spin–orbit coupling. Good agreement between experiment and theory is obtained, especially for the energy threshold dependence of the cross sections.
