 Hi, everyone:
 Since some fellows have same question as I have.

 are three programs are mentioned: pkcal, spartan, sparc

 The program PKalc developed by CompuDrug in Hungray is your best bet. We are
 THE distributor for that particular program.  ACS is not really the source
 for that.

 DelPhi (standardalone and within Insight) can be used to calculate PKa.

 Perhaps a program called SPARC could be of interest....
 SPARC was developed by L.A. Carreira and S.W. Karichoff.

 The CAChe program will allow you to predit PKas if you
 know the Pka of similar molecules. Using project leader,
 you can do least squares analysis of the molecules that have
 known Pka..........................

 The Spartan program( available from wavefunction, Ivring CA)
 will calculate frequencies and display the thermodynamic
 quantities necessary to calculate the change in free energy...
