摘要：

It is shown that the PQ branch of the ν5 fundamental of CH3 35Cl appears to be split because of a vibration-rotation interaction between ν5 and 2ν3, with eventual level crossing in the J structure. This interaction is due to the indirect coupling of ν5 and 2ν3 through common intermediate levels, and especially to the cubic anharmonic coupling of 2ν3 and ν2 and x, y Coriolis coupling of ν2 and ν5. This explanation has been verified by the computer simulation of band contours, and an estimate of the 2ν3 band origin is given. © 1979.
