✦ Synopsis
Correlated molecular mulitpole moments and compact correlated cumulative atomic multipole moment (CCAMM) representation of molecular charge distribution in ground as well as in excited states have been derived directly from multiple reference double-excitation configuration interaction (MRD-CI) wave functions for BH and HzCO molecules using several extended basis sets with multiple polarization functions. This approach extends previously introduced uncorrelated and correlated CAMMs, and allows obtaining inexpensive modeling of electrostatic effects involving molecules in excited electronic states. 0 1992 by John Wiley i 3 Sons, Inc.
