摘要：

The change in heat capacity upon ion solvation Delta(solv) C (p,i) (o) in N-methylpyrrolidone (MP) and in mixed MP-water solvent is presented as the sum of three contributions: electrostatic, cavity formation, and changes in the structure of the solvent. The values for the electrostatic and cavity formation contributions are calculated using model concepts. The values of the structural contribution are determined. The obtained data was analyzed in dependence on the solvent's composition and the electrostatic ion parameters.
