Vibrationally excited 1,1,1-trifluorethane can be produced by radical combination. Subsequent elimination of HF distributes 60-80 kcal of energy between the products. The authors have found that this sequence of reactions produces hydrogen fluoride laser emission: CF3+CH3rarrCF3CH3daggerrarrCF2CH2+HFdagger. Emission has been observed from both HF and DF in nu=1rarr0 and nu=2rarr1 transitions, but no 3rarr2 emission was detected. The observed frequencies, threshold times, and identifications are listed.
