For longer CI expansions a direct CI procedure must be employed. Here the desired eigenvectors are obtained iteratively without explicitly calculating and storing the Hamilton matrix. The basic operation in a direct CI iteration is the evaluation of the residual vectors* y" = (H - E")c" (103) for the required electronic states n. In terms of the molecular integrals and the coupling coefficients y can be written as ij J The coupling coefficients ( @ I I E i j I @ J )and ( @ I I E i j , k l l @ J in ) principle need only be constructed once if they are stored on a formula tape.

Neglecting terms arising from the change of the operator G', these can be approximated by Dri = 2(Gir - Gri) ( 102) Again, this approximation is not appropriate if li) is a valence orbital. H. A Direct Configuration-interactionMethod for Complete Active Space Calculations In the wavefunction optimization procedure outlined in the previous sections the coefficients { c I }can be optimized by any available CI procedure. 28 HANS-JOACHIM WERNER For short CI expansions one could simply construct and diagonalize the Hamiltonian matrices H'".
