SPECIFIC HEAT OF ORGANIC COMPOUNDS AND POLARIZATION EFFECT

Literature data have been considered from the viewpoint of the infl uence of substituents on the mole specifi c heats C_p at constant pressure for 14 series of organic compounds. Using the correlation-analysis method, it has been shown for the fi rst time that experimental and calculated C_p values depend not only on the inductive, resonance, and steric infl uence, but also on the polarization eff ect of variable substituents associated with a constant reactive center. In individual cases the polarization eff ect has the most signifi cant impact on C_p
