Configuration interaction (CI) calculations restricted to single excitations with respect to a closed-shell ground state determinant have been performed using modified CI-Hamiltonian matrix elements. Shifted molecular-orbital (MO) eigenvalues from Kohn-Sham density functional theory (DVI') are used
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
Using a split valence with diffuse and polarization functions full configuration interaction excitation energies, transition moments and polarizabilities have been calculated for CH+. Comparisons have been made with multiconfiguration linear response calculations for various active orbital spaces an
