PACS: 87.15, 87.10, 02.70.N, 33.20.Tp.
Classification: 16.3.

External routines: CHARMM [1].

Nature of problem:
Molecular mechanics force field parametrization.

Solution method:
Fitting of the molecular mechanics potential to normal modes derived from quantum chemical calculations. The missing force field parameters are optimizzed via a merit function to obtain the optimal fit with the reference quantum mechanical set.

Running time:
24 hours. (The test run described in the manuscript takes about 1 minute).
