MULLIK

A full Mulliken Population analysis [41,42] is to be done on the final RHF wavefunction. This involves the following steps:

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

  2. The Coulson-type density matrix, P, is formed.

  3. The overlap population is formed from |$P_{ \\lambda\sigma} S_{\lambda\sigma}$|.

  4. Half the off-diagonals are added onto the diagonals.
