Subject: van der Walls complexes



Hi

	I am posting this on behalf of some colleagues. Can someone point
to any type of calculations (semi-empirical, gaussian, molecular
mechanics) done on van der walls complexes? We tried doing semi-empirical
calculations using HyperChem and most of the procedures required
parameters for Ar, which were not available in the databases. Any help is
appreciated.
