Dear Dr. Kwon,

The Amsterdam Density Functional (ADF) program (http://www.scm.com)  
uses an adaptation of Morokuma's
bond energy decomposition to the Kohn-Sham molecular orbital method,  
which works also for unrestricted calculations.
This leads to a split up of the bond energy in electrostatic energy,  
steric repulsion, Pauli repulsion,
and orbital interactions. The latter are symmetry decomposed according  
to the Ziegler transition state method.

Best regards,
Stan van Gisbergen, Scientific Computing & Modelling
