Influence of the intramolecular interactions on intermolecular potential matrix elements

摘要

General analytical expressions for non-diagonal matrix elements of intermolecular potential operator are found using the theory of linked ordering schemes for ro-vibrational interactions. Non-diagonal matrix elements corresponds the long range electrostatic interactions in the system H_2O-H_2. Earlier the diagonal matrix elements of intermolecular potential operator were obtained. It is calculated the influence of the vibrational anharmonism on the non-diagonal matrix elements of intermolecular potential does not exceed 12%.
