The contour of the v2 Raman band of SF6 liquid has been studied over the temperature range 226–315 K. Reorientational and angular momentum correlation times were obtained by comparing the Fourier transforms of the band contours with the reorientational correlation functions calculated using the J diffusion limit of the extended rotational diffusion model. A reanalysis of Hackleman and Hubbard's nuclear relaxation data for liquid SF6, using the correlation times obtained from the Raman studies, yields the value ± 6.2 × 104 s−1 for the asymmetry in the spin–rotation tensor [Formula: see text] for fluorine nuclei in SF6.

Sulfur hexafluoride (SF6) gas has been used to gas-insulated switchgear (GIS) because of its insulation properties and extinguishing characteristics. The processing of liquid sulfur hexafluoride from cylinders into GIS is endothermic. The processing gas inflation always leads to decrease SF6 gas inflation speed due to the lack of heat supplement and the infiltrated moisture will stick on the GIS equipment, especially at the valve outlet. In the paper, a heater detection device for sulfur hexafluoride (SF6) steel cylinder is developed. The new heater device will monitor and display the specific temperature and humidity of the valve outlet instantaneously and then heat and dry the sulfur hexafluoride (SF6) steel cylinder with automatic and stability. Then it helps to speed up the sulfur hexafluoride gasification. Meanwhile, the whole device is portable in safety.

Observational Techniques

The focus of discussion in Working Group 3 was on the Thermodynamic Properties as determined spectroscopically, including the observational techniques and the theoretical modeling of physical processes responsible for the emission spectrum. Recent advances in observational techniques and theoretical concepts make this discussion particularly timely. It is wise to remember that the determination of thermodynamic parameters is not an end in itself and that these are interesting chiefly for what they can tell us about the energetics and mass transport in prominences.
