summary of energy decomposition method

Dear CCLers;
 The summary of the answers for my question about energy decomposition
 methods is as follows.

 One such possibility is Gamess(USA) for Morokuma energy decomposition

 The NBO package (NBO 5.0, allows to run
 energy decomposition analysis (NEDA). The energy decomposition is
 calculated in a
 different way with respect to Morokuma analyses (see bibliography from
 GlendeningTimes New Roman). It does often converge easier and faster. I
 the method particularly for big or complex systems. The program can be
 to GAMESS(US), GAUSSIAN and other QM packages.

 Dear Dr. Kwon,
 The Amsterdam Density Functional (ADF) program (
 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,

 you can use the Program Apost by Istvan Mayer a posteriori if you have
 see the readme files there and an accepted paper
 "An exact chemical decomposition scheme for
 the molecular energy" by Istvan Mayer, which will appear in Chem. Phys.

 Besides the Morokuma analysis there is also the CSOV (Constrainded Space
 Orbital Variations) energy decomposition analysis from Paul Bagus. It
 allows you to decompose the interaction energy between two fragments in
 terms of polarization of each fragment an charge transfer from one
 fragment to the other one. It is currently implemented in the HONDO
 program and currently I'm working in extending the analysis to allow one
 of the fragments to be described by a multireference wavefunction. If
 you are interested let me know.
