Laser induced fluorescence excitation spectroscopy has been used to determine the previously ambiguous assignments of A-state stretching frequencies of CF2 radical under supersonic free jet conditions. The measured frequencies are v’1=1012.1±0.5cm-1, v’3=1180.2±0.5cm-1, which is in good agreement with Cameron's[6] calculation result. Furthermore, some transitions attributed to the (1,n-2,0)←(0,0,0), n≦6 progressions are first reported, and new parameters are derived from the spectra obtained. 相似文献
