摘要：

Fluorescence excitation and dispersed fluorescence spectra of the X 2E-A 2A1 transition of the trifluoromethoxy radical have been measured using laser excitation in the range 336-358 nm. The spectra are dominated by the features of the CO stretching and the OCF deformation mode. The LIF technique has been used to study the kinetics of the reactions of CF3O(X 2E) radicals with CH4 (5) and C2H6 (6). Rate coefficients of k5=(2.2 +/- 0.2) x 10(-14) and k6=(1.2 +/- 0.2) X 10(-12) cm3/s at 298 K have been determined.
