SDTC.I. — Specify CI-active MOs in a SDT-CI calculation.
SDTC.I.=n
SDTC.I.(n,m
)
n
Use the n orbitals bracketing the SCF HOMO, possibly after MO reordering using
RECLAS(n,m
), as
the CI-active MOs in a SDT-CI calculation (microstate space has only single, double and
triple excitations). The number of occupied CI-active MOs will be n / 2 + 1 if n is odd and
n / 2 if n is even. All of the partially occupied MOs should be included in the active
space.
n,m
)
Use orbitals n through m, possibly after MO reordering using
RECLAS(n,m
), as
the CI-active MOs in a SDT-CI calculation (microstate space has only single, double and
triple excitations). All of the partially occupied MOs should be included in the active
space.
