摘要

Chemical HCl and HF laser emissions were observed from the competitive, four-centered unimolecular elimination reactions of chemically activated ClFHCOH, Cl2FCOH, and ClF2COH molecules in an optical cavity. The HF emission was found to be significantly stronger and was observed in all three reactions; the HCl emission, however, was detected only in the Cl2FCOH system. This is attributable to a larger stimulated emission coefficient as well as a preferentially faster rate of elimination of HF than HCl. The vibrationally excited methanol molecule, which possesses at least 130 kcal/mol of internal energy, was generated by insertion of an O(1D) atom into a C-H bond of a chlorofluoromethane molecule. The O(1D) atom was produced from the flash-photolytic decomposition of O3. The initial population ratios of the highest gain transitions have been estimated and compared with the values obtained from other O(1D) atom insertion-elimination reactions reported previously.
