Paper Abstract

In the given paper the correct model for intermolecular potential is proposed. The model takes into account the vibrational dependence of inter- and intra-molecular distances. To create the model the Lennard-Jones atom-atomic potentials are used. In the framework of our model the Talor expansion is applied for vibrational coordinates. Isotropic terms of intermolecular potential are only taken into account. As a result the correct expressions for intermolecular potential of HF-Ar colliding system is found. The contribution of vibrational dependence into the line shift was estimated. Thus, the vibrational corrections for Robert-Bonamy formalism are obtained. Our model allows one to calculate most exactly the line shifts in near infrared and visible ranges.
