✦ Synopsis
An earlier analytical. approsimative result for the semi-classical, sudden limit of energy dependentin -+_i cross sections of rotational relaxation of homonuclear. diatomic molecules perturbed by an atom has been integrated to obtain dynamical fitting of temperature dependent rate coefficients. The result can be written by using two parameters, kao = [(Zj + l)/ (2jo + 1)]1'2 a (Ii -11-tb), where the parametersa and b are given from the assumed intermolecular potential, the reduced mass for the collisions and the temperature. A comparison with several esperimentf results proves the validity of the above espression and gives some statements about the intermolecular potentials for the systems considered.
