✦ Synopsis

High-resolution infrared spectra of the m 6 fundamental asymmetric axial S-F stretching vibrational mode of 32 SF 4 have been recorded in absorption at 296 K using a Fourier-transform infrared (FTIR) spectrometer. The band is centred at 729.7 cm Γ€1 . In total, 1550 a-type vibration-rotation transitions have been assigned. Analysis of the data has yielded precise spectroscopic constants for the m 6 ΒΌ 1 state, as well as revised constants for the ground vibrational state. Other features in the FTIR spectra are attributed to difference-band transitions from excited vibrational levels of the m 4 and m 9 vibrational modes.

Infrared absorption spectra of the Ξ½ 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 Ξ½ 1 fundamental being assigned
