 I should point out that HyperChem *does* have semi-empirical parameters
 for Ar for Extended Huckel, CNDO, and INDO.  But if Ar parameters have
 been published for any of the other semi-empirical methods that meet our
 usual criteria (refereed journals, etc.), we'd very likely be interested
 in including them in our databases.
