Abstract:

Laser double resonance experiments in HF were extended to probing levels as high as J13 to define the processes of population transfer between rotational levels and transfer from vibration to rotation. In the first part of this report rotational transfer experiments are described and the results are compared with three different kinetic models. Using the criteria of transfer rates and signal shapes for evaluation, the Polyani-Woodall model was found to best describe the data. The second part of the report describes observations of direct transfer of vibrational V1 transfer to rotational levels J10-13 of V0. Very fast transfer by this route was measured but only a small fraction of the V1 population was involved. Dilution of the HF sample by rare gases was found to enhance V-R transfer in accord with observations reported for rotational HF lasers.
