Name

MULLIKEN — Perform a pseudo-Mulliken population analysis.

Synopsis

 MULLIKEN 

Description

A full Mulliken-type Population analysis is done on the final RHF wavefunction. This involves the following steps:

  1. the number of microstates at each stage of the selection procedure

  2. The eigenvector matrix is divided by the square root of the overlap matrix, S

  3. The Coulson type density matrix, P, is formed from the modified eigenvector matrix.

  4. The overlap population is formed from Pij * Sij

  5. Half the off-diagonal terms are summed into the diagonal terms.
