Description
The far-infrared spectrum of CD$_{3}$SH has been recorded from 60 to 450 cm$^{-1}$ at the FIR beamline of the Canadian Light Source in Saskatoon in order to explore the evolution of the torsional structure in climbing up the ladder of torsional states. So far, the torsion-rotation levels have been extensively mapped up to the third excited torsional state, and we hope to push the assignments further up to the v$_{t}$ = 4 state and beyond to where the ground torsional ladder is passing through the lower vibrational levels with the possibility of interesting torsion-vibration interactions. Here the torsional levels are high above the potential barrier to internal rotation and are essentially free rotor states following the parabolic curves of our “Universal Spectral Predictor”. We wish to explore how well the free rotor pattern can be modeled in order to gain predictive power for extrapolation up to higher states and potentially address the long-standing torsional problem of simultaneous global fitting of ground and vibrational states.
