Laser-induced fluorescence (LIF) excitation spectrum for gas-phase dichlorocarbene (CCl2) cooled in a supersonic free jet has been observed in the wavelength range of 497-517 nm. The K-structure was clearly resolved. About 80 subbands were assigned to (v1, v2 0)←(0, 0, 0) vibronic transitions. The vibrational frequencies of ν′1=643.5 cm-1, ν′2=308,0 cm-1 and their anharmonic constants were obtained. Furthermore, the rotational data A′-B′=3.67 cm-1, A″-B″=1.80 cm-1 were deduced from the spectral analysis.
