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 $A ?^{1} A″(nπ^{1}) ← X ?^{1} A′$ and $a ?^{8} A″(n, π^{1}) ← X ?^{1} A′$ 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 $A ?^{1} A″$ state has been evaluated to be 1556.0 ± 45 cm^?1.
