✦ Synopsis

Infrared absorption spectra of the ν 1 axial S-F stretching vibrational bands of sulfur tetrafluoride, SF 4 , have been recorded and analyzed. A diode-laser jet spectrometer was used to record high-resolution spectra of 32 SF 4 , with 87 vibration-rotation lines of the ν 1 fundamental being assigned. Least-squares fitting of the data yielded a precise vibrational band origin, as well as rotational parameters for the upper state. In addition, lower-resolution spectra of a static sample of SF 4 held at room temperature were recorded using a Fourier transform (FTIR) spectrometer. The progressions of prominent features observed in the roomtemperature FTIR spectra are attributed to summation bands arising from ν 1 transitions from excited vibrational levels of the low-frequency ν 4 manifold of both 32 SF 4 and 34 SF 4 .
