Research Abstract

We have develped the multilevel fragment molecular orbital method in which effective fragment potential (EFP), molecular mechanics (MM), and polarizable continuum solvent model (PCM) have been interfaced with the the fragment molecular orbital (FMO) method. The method facilitates geometry optimizations and molecular dynamics simulations of large molecular systems and is expected to be usuful in simulation studies of biomolecules.
