Introduction A series of theoretical studies on the vibrational characteristics of small, related molecules were made in the last years in this laboratory in order to revise the published wavenumbers and their assignments. Such studies resulted in some cases in the modification of the reported assignments. Doubtful or incomplete sets of wavenumbers were also found for some molecules in the literature and in these cases new infrared and Raman measurements were made. The revised wavenumbers were subsequently used to calculate consistent sets of force constants using the Scaled Quantum Mechanics (SQM) force field approach [1]. These studies are now extended to the members of the CF3SX series, with X
