Chemical HCl laser emissions were observed in the four-centered unimolecular elimination of HCl from vibrationally excited Cl3COH, Cl2HCOH, and ClH2COH molecules in an optical cavity. 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 chloromethane molecule. The O(1D) atom was produced from the flash-photolytic decomposition of O3. The vibration-rotation transitions of the laser emission were identified, and the initial populations ratios of the highest gain transitions have been estimated.
