Vibrational relaxation of hexafluoride compounds: MoF6, ReF 6, SeF6, and WF6
The Journal of Chemical Physics
Ultrasonic attenuation has been measured in MoF6, ReF 6, SeF6, and WF6 at 293 K. In all cases, a single relaxation process was observed and attributed to the total vibrational energy of the relaxing molecule. Isothermal relaxation times were found to be 2.8 × 10-8, 8.8 × 10-9, 2.9 × 10 -7, and 2.3 × 10-8 s atm for MoF6, ReF6, SeF6, and WF6, respectively. Assuming series relaxation, those relaxation times can be converted to the number of collisions required for relaxation Zvib. The values of Z vib vary with the energy of the lowest vibrational mode as expected from the simple Lambert-Salter correlation. © 1982 American Institute of Physics.
