A new method for approximate estimates of the dispersion interaction between two molecules

  • Gunnar Karlström
Original Investigations


A new method to evaluate the dispersion interaction between two weakly interacting closed shell molecules is presented. The method is based on a second-order sum-over-states perturbation method, where the nominator is approximated by products of one electron integrals.
