Name
AM1-FS2 — Use AM1 Hamiltonian plus AM1-FS2 dispersion and hydorgen-bond corrections.
Description
The AM1-FS2 method is identical to an ordinary AM1
calculation except that extra terms for dispersion and hydrogen bonding are added using the AM1-FS2
model.
It supports all elements supported by AM1 except Hg. When
it is used with C.I. (explicit or implicit), the analytic gradients will not be exact (use
DERINU if needed).
