Hybrid procedure for the treatment of large molecular systems.
A crucial part of the system (e.g., the
chromophore and its surroundings)
is treated explicitly by quantum mechanical (
QM) techniques, whereas the rest of the system
is approximated by a classical or molecular mechanics (
MM) force field treatment.
Note:
Sometimes called QC/MM.
