Traint

Traint is used to transform integrals for post-HF and TDDFT.

General keywords

FROZ

The numbers of frozen core orbitals in $nreps irreps. 1 ≤ $nreps ≤ 8 since only Abelian group symmetry is supported.

DELE

The numbers of virtual orbitals to be deleted in $nreps irreps. 1 ≤ $nreps ≤ 8 since only Abelian group symmetry is supported.

ORBI

For CISD and other single reference method, input HFORB; For MRPT2, MRCI and other multi-reference method, input MCORB

Example:

Orbital
mcorb

MRPT2

The keyword for MO transformation to J (ij|rs) and K (ir|js) operators and (ia|bb) and (ib|ab), otherwise for full MO transformation.
