Localmo
Molecule orbital localization module.
Contents
LocalMO is used to localize molecular orbital. Boys localization and trust region localization approaches are supported.
General keywords
Boys
Boys localization approach. This is default localization functional.
Mboys
Modified Boys localization approach. Next line is an integral to set powern. For example:
Mboys
- 2
4CENT
Four-center momentlocalization approach. Next line is an integral to set powern. For example:
4CENT
- 1
Pepik
Pepik-Mezey localization approach.
Thresh
Two float point number to give threshold of localization. For example:
Thresh
- 1.d-8 1.d-8
Maxcycle
Maximum number of iterations allowed for Boys localization.
Rohfloc
Localize ROHF/ROKS orbitals
mcscfloc
Localize MCSCF orbitals
Orbital
- next line inputs 'hforb' for SCF localization or 'mcorb' for MCSCF localization. Default does not input this keyword.
Flmo
Project LMO to pFLMO, which is needed to the next least-change localization.
Frozocc
Frozen occupied orbitals. Next line is an integral to set frozen orbital number. For example:
Frozocc
- 10
Frozvir
Frozen virtual orbitals. Next line is an integral to set frozen orbital number. For example:
Frozvir
- 10
Analyze
Analyze LMO orbitals. This keyword will calculate sum|i||a| and Molecular Orbital Spread (MOS). It needs to have file with name of $BDFTASK.testorb and this file is format file like scforb and casorb. Next line is an two integral to set occupied orbital number. For example:
RHF : set alpha and Beta orbital number. Analyze
- 10 10
ROHF or UHF : set alpha and Beta orbital number for spin multiplicity (2S+1) = 3. Analyze
- 11 9
MCSCF : set inactive (doubly occupied) and active orbitals for CAS(4,4) Analyze
- 8 4
Iapair
One float point number to give threshold of cutoff sum|i||a|. Default : 1.d-4
For example:
Iapair
- 1.d-3
Momatch
Match two type MOs with format name of $BDFTASK.testorb and $BDFTASK.checkorb, respectively. If use UHF/UKS, it is default to match alpha and Beta orbital. If do not exist $BDFTASK.checkorb , this keyword will be skipped.
