Vibrational Relaxation of HCl (v = 1,2,3,6) by H and Cl Atoms,
Abstract
Rate coefficients are calculated for the collisional de-excitation of vibrationally excited HCl molecules by H and Cl atoms. Three-dimensional classical trajectories of the collisional dynamics of these reactions are calculated by using London-Eyring-Polanyi-Sato (LEPS) potential-energy surfaces. The results indicate that (1) the rapid deactivation of vibrationally excited HCl by H and Cl atoms can be explained if bound complexes are postulated for both HClH and ClHCl, (2) H- and Cl atom exchange are efficient mechanisms for relaxing vibrationally excited HCl by Cl and H atoms, respectively, (3) multiple quantum-transitions are important in these de-excitation processes, and (4) the major energy transfer processes are vibration to translation in the deactivation of HCl by H atoms and vibration to rotation in the deactivation of HCl by Cl atoms.
