摘　　要：Laser induced fluorescnece excitation spectroscopy has been uded to determine the pre-viously ambiguous assignments of A-state stretching frequencies of CF2radical under supersonic free jet conditions.The measured frequencies arewhich is in good agreement with Cameron’s[6]calculation result.Furhtermore,some transitions attributed to the progressions are first reported,and new parameters arederived from the spectra obtained.Laser induced fluorescnece excitation spectroscopy has been uded to determine the pre-viously ambiguous assignments of A-state stretching frequencies of CF2radical under supersonic free jet conditions.The measured frequencies arewhich is in good agreement with Cameron's[6]calculation result.Furhtermore,some transitions attributed to the progressions are first reported,and new parameters arederived from the spectra obtained.
