Abstract

Abstract A recently developed ‘quasiclassical ECS-E’ fitting law for rotational transition rates has been used for a detailed comparison of theoretical and experimental data on rotational energy relaxation in nitrogen. A wide range of data on line broadening coefficients, ultrasonic absorption, population kinetics of isolated rotational levels exposed to laser pumping and population kinetics in a free jet has been analysed in order to refine the effective intermolecular parameters of the model thus providing a temperature-dependent form of the fitting law from 35 up to 1500 K.
