INFRARED DIODE-LASER SPECTROSCOPY OF THE NF2 RADICAL

The ν1 and ν3 bands of NF2 (X2B1) have been measured around 1100 and 930 cm-1 with tunable infrared diode lasers. Many RQ and RR components have been identified in the ν1 band and a doublet splitting due to spin-rotation interaction is resolved in most of the transitions studied. Analysis of the ν1 spectra yields preliminary values for the change in 1 2(B + C) on vibrational excitation and for the largest component of the spin-rotation tensor, ε{lunate}aa, for the upper vibrational level. © 1979.
