H+CLCN yields HCL+CN: Product Excitations and Reaction Mechanism at E(c.m.) approx. 21.6 kcal/mol

摘要

The study of energy disposal in chemical reactions is of fundamental importance for understanding reaction dynamics, and therefore a number of experimental techniques have been developed which allow direct spectroscopy observations of nascent products. Recently, sub-Doppler spectroscopy has been used in conjunction with laser induced fluorescence (LIF) detection, in order to determine electronic, vibrational, rotational, and translational (E, V, R, and T) energy disposal in bimolecular reactions, and kinetic energy distributions have been obtained for specific product quantum states. This provides quantitative information about exit channel interactions for the reactive channel(s) being sampled. Such data correlate internal and translational degrees of freedom and are more valuable than the separate distributions. In this paper, we present and discuss V,R,T distributions for nascent CN(X2 sigma) produced from the reaction of H atoms with C1CN at a center-of-mass (c.m.) kinetic energy of approximately 21.6 kcal/mol (7560/cm).
