INTEGRATED INFRARED INTENSITIES AND TRANSITION MOMENTS IN $SF^{6}$
Publisher:
Ohio State UniversityAbstract:
The integrated infrared band intensities of the fundamental vibrational modes in $SF_{6}$ have been measured by the Wilson-Wells-Penner-Weber method. The results are $1361\pm 34$ km $mol^{-1}$ for the fundamental at $948 cm^{-1}$, and $74\pm 2$ km $mol^{-1}$ for the fundamental at $615 cm^{-1}$. The transition moments derived from these measurements are $0.437\pm 0.025$ Debye for the $948 cm^{-1}$ fundamental and $0.126\pm 0.003$ Debye 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 $0.42\pm 0.03$ Debye, in good agreement with the value found from band intensities.
