SolvMol software program performs calculations of: (i) the free energy of polar solvation, (ii) reorganization energy of an electron transfer reaction, and (iii) Stokes-shift dynamics. The molecule dissolved in polar liquid is defined by coordinates of its atoms or atomic groups and a set of partial charges. The partial charges of the solute interact with dipoles of the polar solvent which undergo translational and rotational thermal motions. The algorithm incorporates the molecular structure of the solvent in terms of a set of correlation functions. The current implementation is based on the density correlation function calculated from the Percus-Yevick solution for hard spheres of the same density and two correlations functions of dipolar orientations: longitudinal and transverse structure factors. These latter are obtained from experimental input for a given solvent (dielectric constant, density, dipole moment, polarizability, etc.) by using our analytical calculation scheme. The properties of 87 commonly used molecular liquids and of some force-field solvents (SPC/E, TIP3P) are included in the solvents database. The code has the capability to calculate the solvation free energy and the difference of solvation free energies in two redox states at different temperatures.
