INTRAMOLECULAR AND DISSOCIATION DYNAMICS OF THE CF2BR RADICAL

Classical trajectory methods were used to investigate the nature of the intramolecular dynamics (quasiperiodic vs chaotic) of the CF2Br radical. The potential energy surface is based on empirical and ab initio results. Power spectra show that the Br-C-F bend exhibits quasiperiodic dynamics while the other modes are chaotic. Despite the presence of quasiperiodic dynamics, the dissociation rates for mode-specific excitations of the normal modes are essentially the same as those for equipartitioning of the excitation energy among all the normal modes.
