摘要：
The laser-induced fluorescence excitation spectra of jet-cooled CuF have been recorded in the range of 19000-21470cm(-1), in which the CuF radicals were produced by the reaction of SF6 with copper atoms from a dc discharge-sputtering source under supersonic jet conditions. Eight observed vibronic transition bands have been assigned as the transition from the ground state X((1)Sigma(+)) to B((1)Sigma(+)), C((II)-I-1) and an unreported upper state. The rotational structure of all observed bands has been analysed at the estimated rotational temperature 80K. We determined the newly observed band to be the ((II)-I-1, v = 1)-X((1)Sigma(+)v = 0) transition according to the character of the rotational structure and the isotopic shift analysis. In addition, the lifetimes of the states involved in these bands were measured.
