Abstract
The commonly used generalized multipole expansion is divergent if applied on the description of pair interaction of large molecules in condensed phases. In the present series of papers a new convergent expansion of pair molecular interaction is therefore proposed and studied in detail.
In the first paper of the series a possible convergent expansion of site-site interaction is derived. In contrast to multipole series the new expansion is shown to converge for all configurations with finite value of the site-site interaction. The convergence conditions of the series are studied in detail for electrostatic term as well as for higher terms of the perturbation expansion of interaction.
