Rotational population transfer in DF
Abstract
Collisional transfer of population between rotational levels of DF was measured using an ir double resonance method. The data were used to calculate rotational rates. Pressure broadening of DF absorption was determined for the fundamental lines P6 through P18. Total molecular collisional rates were obtained from the absorption data and compared with the total of individual collisional rates for velocity, vibrational and rotational relaxation. The results were compared with two kinetic rate models. Observations were also made of rotational lasing and vibration to rotation transfer in DF.
