Abstract

We present terminal population of seven vibrational levels, v"=1-8, in Na2 supersonic beam formed by pure Sodium expansion. It was determined by the laser induced fluorescence method for source pressure x nozzle diameter product p0d=0.32, and covers 550-1550cm' energy range. The population forms a continuous, non-thermal dependence of the internal energy, and does not depend much on the partitioning of this energy between vibration and rotation. We think, that this new result is not in contradiction with observation of previous experiments, but suggests new interpretations.
