Integrated infrared intensities and transition moments in SF6

Abstract

The integrated infrared band intensities of the fundamental vibrational modes in SF6 have been measured by the Wilson–Wells–Penner–Weber method. The results are 1361±34 km mole−1 for the fundamental at 948 cm−1, and 74±2 km mole−1 for the fundamental at 615 cm−1. The transition moments derived from these measurements are 0.437±0.005 D for the 948 cm−1 fundamental and 0.126±0.002 D for the 615 cm−1 band. The transition moment was also derived from single line strengths in the 948 cm−1 band and found to be 0.42±0.03 D, in good agreement with the value found from band intensities.
