Abstract
We have calculated the rotational energy transition probability upon collision using approximate results from a previous distorted wave calculation. For heavy homonuclear diatomic molecules, i.e. molecules with molecular weight >20, the mean transition probability is approximated by ½(d0/r0)2, where d0 is the internuclear distance and r0 the kinetic collision diameter. This expression is in agreement with relaxation times as calculated from shock wave data.Keywords
