WebQM/MM papers since we shall quote only a small selection of these in the following. The QM/MM approach is by now established as a valuable tool for modeling large biomolecular systems, but it is also often applied to study processes in explicit solvent and to investigate large inorganic/organometallic and solid-state systems. Methodological Web[27,28] In these cases, multiscale QM/MM approaches are required, involving accurate electronic methods to eval-uate the chiral properties as well as accurate dynamic simulations to reliably describe the solvent ﬂuctuations, which sustain the chiral response in the solvent cage around the chiral solute.
