Abstract The experimental temperature dependence of alkali-N2 quenching cross sections is explained semi-quantitatively by a simple theoretical model, based on an ionic intermediate state, in which attractive van-der-Waals forces play an essential role. Using this model, quenching experiments are compared with Na(32P)-N2 excitation measurements in molecular beams. From this comparison it is concluded that the distribution of relative cross sections for specific vibrational transitions during the quenching process can be described by a distribution calculated by ,(8) whereas the distribution given by (18) has to be rejected. Resonant vibrational-electronic energy transfer is not important.
