摘要：

Vibrational spectra of benzothiophene and benzothiazole in the gas and liquid states are examined using FTIR and Raman spectroscopy in the region from 100 to 4000 cm(-1). Polarization measurements of the vibrations in the liquid are taken using Raman spectroscopy. All of the fundamentals are assigned and a nearly complete set of vapor wavenumbers is obtained for both molecules. The establishment of the two far-IR fundamentals for benzothiophene and benzothiazole should significantly improve the agreement between the calorimetric and spectroscopically calculated ideal-gas entropies. The vapor-phase spectra reveal a few cases of minor Fermi resonance. The vapor-liquid wavelength shifts are discussed, including the difference between the planar and non-planar modes.
