## Abstract Oneβelectron properties may be evaluated by configuration interaction methods using analytical differentiation of the total energy with respect to an external perturbation parameter. Dipole moments are reported using such a method for CO and H~2~CO. Inclusion of single substitutions doe
Recently a new direct CI method was proposed by Siegbahn. In his approach a large list of formulas containing one-electron coupling coefficients is made, creating storage problems and high I/O rates. A method to calculate these coefficients is described and tests performed showing that on the CRAY-1
