Rotational Population Transfer in HF.
Abstract
Population transfer in HF was measured by an IR double resonance experiment which uses HF pump and probe lasers. In three kinds of experiments populations pumped to a specific rotational level were followed: out of the pumped level, to the levels above, and to the levels below. The rates of loss from the pumped level and transfer to the lower levels were strongly affected by lasing between rotational levels. Measurements were made of gain and laser intensity and that information was incorporated into a kinetic rate model to assess contributions to the total transfer rates. The collisional contributions are compared with linewidth data. Information was also obtained on population transfer rates for velocity cross relaxation and for vibration-rotation transfer. (Author)
