Abstract
The failure of the electron gas model calculation of the Ar–N2 interaction potential at large intermolecular separations [J. Chem. Phys. 68, 5001 (1978)] is remedied by using a model developed earlier by one of the present authors and Gordon. The results give predictions of the Ar–N2 interaction potential for the entire portion of physically interesting region of the potential surface. The spherically averaged potential is compared with the available experimental potentials and shows the improved agreement.
