The influence of vibrational excitation of absorbing molecule on the intermolecular potential parameters is considered. It is proved that the vibrational dependence of intermolecular potential must be taken into account when the line shift of molecular absorption lines are calculated. The modern technique of the summation of perturbation theory divergent series are used for intermoleular potential series. First, non-diagonal Pade approximant is obtained for intermolecular potential expansion over intermolecular distance for the collision of two helium atoms.
