Analysis of the Ã1A″ ← X∼1A' electronic transition in thiocarbonyl chlorofluoride
Abstract
The visible absorption spectrum of thiocarbonyl chlorofluoride, ClFCS, in the region 5000 to 3000 Å has been observed under conditions of high resolution in the vapor phase and has been assigned to the Ã1A″(nπ ∗) ← X∼1A' and ã8A″(n, π ∗) ← X∼1A' electronic transitions. All six fundamental modes have been assigned for both the upper and lower singlet electronic states. From the observed splittings of the even-odd quanta of ν6' in the spectrum the barrier to inversion in the Ã1A″ state has been evaluated to be 1556.0 ± 45 cm -1.
