Toolkit for computational chemistry

This toolkit is designed to provide a user-friendly interface for users with or without a theoretical chemistry background to calculate missing parameters (i.e., log K) required for their particular speciation problem. Only input files are generated for quantum chemical programs. The user must locate the quantum chemical packages themselves and run their calculations locally. As listed below, there are four independent modules. Users may use them separately or in combination. Please note that we have not yet implemented the means to input the calculated results into PHREEQC.


a) Conformational search
b) Solvation free energy (ΔGsolv) calculation
c) Proton dissociation constant (pKa) calculation
d) Stability constant (log K) calculation
