174. CNDO/S-CI: Molecular Orbital Calculations with the
Complete Neglect of Differen- tial Overlap and
Configuration Interaction
by J. Del Bene, H. H. JaffO(e,+), R. L. Ellis, and G. Kuehnlenz, University of Cincinnati, Cincinnati, Ohio 45221 This program performs molecular orbital calculation for molecules in closed-shell electronic configurations using the CNDO/S method described by J. Del Bene and H. H. JaffO(e,+), J. Chem. Phys., 48, 1807 (1968), with the following revisions: 1. The two-center two-electron repulsion integrals are calculated by the Mataga approximation. 2. The CI matrix is symmetry blocked. Up to 31 centers and 100 basis members can be employed, and the program requires a computing system with an overlay facility.
