Schrodinger do a pKa calc that is a QSAR using QM results. There was a good
 paper in J.Amer.Chem.Soc last year on ab initio calcs to predict pka. It's a
 difficult area as the slightest error will give erroneous results.

 Hello,
 I am wondering if anyone would know of any programs that can calculate
 pKa's quantum mechanically.  I think ChemCad calculates them
 semi-empirically, but I would prefer a QM method.
                             Thank you,
                                  Jean
