Abstract

Photodepletion and action spectra of the laser-induced Ba⋯FCD ₃ fragmentation have been measured over the 16 075-16 380 cm ^-1 range. The observed band and peak structures allowed us to estimate the vibrational and rotational structures of the excited complex at the transition state configuration. The relative reaction probability P _R(E) for the intracluster Ba⋯FCD₃+hv→BaF +CD₃ reaction has been determined over the cited energy range. P _R(E) shows a peak structure with an energy spacing of 8.9 cm ^-1 which was attributed to an internal rotation of the CD₃ group in the intermediate state. A comparison with previous Ba⋯FCH ₃ photofragmentation spectra reveals the dynamical role of the internal CX₃ (X=H, D) motion which is manifested by the presence of rotational resonances in the laser-induced intracluster reaction.
