Intramolecular isotope effect in laser multiphoton dissociation of CH_2DCH_2Cl
Abstract
The ratio r = [HCl]/[DCl], for the decomposition of ethyl 2d_1 chloride, CH_2DCH_2Cl, induced by intense CO_2 laser beams, has been measured under different experimental conditions. Changes in beam energy, beam geometry, rotational lines, irradiation time and pressure have no discernible effect on r. It is shown that a narrow distribution with an average excess energy of E+V = 15 ± 2 photons (35–46 kcal/mole) and RRKM theory are mutually consistent with the observed value of r = 2.6 ± 0.1. The implications of these results for the mechanism of multiphoton absorption are analyzed.
