HONDOPLUS version 5.2
Introduction to HONDOPLUS
HONDOPLUS is a modified version of the HONDO-v99.6 electronic structure program. HONDOPLUS began as HONDO/S, with solvation methods added to HONDO. As additional capabilities were added, not related to solvation, the name was changed to HONDOPLUS.
As compared to HONDO, the HONDOPLUS program has enhancements in the following areas:
- Major new capabilities
- new methods for calculating partial atomic charges
- intruder state avoidance in MRMP2 and MC-QDPT
- Other enhancements
- additional basis sets
- user-defined density functionals
- improved portability
- improved manual
- more complete test suites.
A list of capabilities of HONDO is given in the "Overview of HONDO" section of the manual. The
enhancements in HONDOPLUS are summarized above and are described in detail in the revision summaries
in the "What's New" sections of the manual. The major new capabilities are summarized next:
Major capabilities added in HONDOPLUS
The fourfold way is a method of diabatization of coupled electronic states based on defining diabatic
molecular orbitals (DMOs), re-expressing CASSCF or MC-QDPT wave functions in terms of DMOs, and
transforming to diabatic configuration state functions by configurational uniformity. The diabatic
states span the same space as N adiabatic states, which may be the N lowest-energy adiabatic states,
or the ground state may be excluded. There are three options:
The program also computes the diagonal and off-diagonal elements of the diabatic potential energy matrix.
- diabatize CASSCF wave functions based on state-averaged CASSCF DMOs
- diabatize MC-QDPT wave functions based on MC-QDPT DMOs
- diabatize MC-QDPT wave functions based on state-averaged CASSCF DMOs.

Universal solvation models may be applied to almost any solvent.
- the analytic surface area (ASA) algorithm for solvent-accessible surface areas and their gradients
- the generalized Born approximation (GBA) for implicit-solvent calculations of free energies
of solvation the following universal generalized Born solvation models:
- SM5.42R and SM5.42
- SM5.43R and SM5.43
