摘　　要：在27l～279 nm波长范围内采用REMPI技术研究CC1自由基的A^2△光谱.实验观察到12~C^35C1以及同位素分子12~C^37C1的A^2△←x^2Ⅱ_1/2,0-0,1-0和2-1跃迁谱带,其中2-1的跃迁为新观察到谱带.获得了A^2△←X^2Ⅱ_1/2电子跃迁0-0,1-0,2-1谱带的同住素位移.The resonance-enhanced multiphoton ionization （REMPI） spectra of ^12C^35Cl and isotope ^12C^37 Cl have been investigated in the single-photon wavelength region of 271=279 nm. 0--0,1--0 and 2--1 bands of the A^2△←X^2∏1/2 electronic transition were observed in this study and the 2--1 band was first reported. In addition, the isotope shifs of 0--0, 1--0, and 2--1 bands were measured.
