Far-infrared spectra and barriers to internal rotation of isopropyl alcohol and alkyl mercaptans

Far-infrared spectra of isopropyl alcohol, ethyl mercaptan, isopropyl mercaptan, tert-butyl mercaptan, and their deuterated analogs have been examined. The observed torsional transitions are interpreted with a potential function of the form V = 1 2 Σ kV k(1 − cos kα) . The obtained energy difference...

Summary:Far-infrared spectra of isopropyl alcohol, ethyl mercaptan, isopropyl mercaptan, tert-butyl mercaptan, and their deuterated analogs have been examined. The observed torsional transitions are interpreted with a potential function of the form V = 1 2 Σ kV k(1 − cos kα) . The obtained energy differences are in good agreement with those determined from calorimetric data. The coupling of torsional vibration with other low frequency vibrations is discussed.
