Calcule of the thermodynamics properties of complexs



Hi,
   I am carrying through calculation of thermodynamic properties of
 complexes of zinc and cadmium, using the PC Spartan Pro that
 calculates these properties from the vibracionais frequencias of the
 complexes.
   It would like to know, if possible, which are the
 computational methods of calculation for the thermodynamic properties
 and in the coordination composite case which would be most
 trustworthy. It would like if possible references.
                                     Thanks
