Inverse Raman spectrum of the ν1-fundamental of CF 4
Abstract
We have obtained fully resolved spectra of the ν1 ( Q-branch) band of CF 4 at a pressure of 4 Torr using a variation of stimulated Raman spectroscopy. With an experimental resolution of ≤0.004 cm -1, no detectable tensor splitting of the rotational levels exists up to J = 55. The spectrum is readily fit with a band origin α = 909.0720 cm -1 and a single rotational term β - β0 = -3.417 × 10 -1cm -1. We have also observed an underlying hot band, which we tentatively assign as the ν1 + ν2 ← ν2 transition, with α' = 909.1997 cm -1 and ( β - β0)' = -3.405 × 10 -4cm -1.
