Infrared Laser Spectroscopy of Free Radicals and Ions. III. The ν_3 Band of NF_2 (tilde{X}^2B_1)
Abstract
The ν_3 band of NF_2(tilde{X}^2B_1) has been measured at high resolution by using tunable diode lasers. Rotational, distortion and spin-rotation constants have been derived for the ν_3 = 1 state by using ground state constants derived earlier from analysis of the ν_1 band. The position of the band centre, not previously measured, is 942.481 53(30) cm-1. Analysis of the ν_1 - ν_3 Coriolis interaction yields the Coriolis coupling constant ξ_13 = 0.698(10).
