SC.I. — Specify CI-active MOs in a S-CI calculation.
SC.I.=n
SC.I.(n,m
)
n
Use the n orbitals bracketing the HOMO, possibly after MO reordering using
RECLAS(n,m
), as
the CI-active MOs in a S-CI calculation (microstate space has only single 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 S-CI calculation (microstate space has only single excitations). All
of the partially occupied MOs should be included in the active space.
