Abstract
The published data on the enthalpy of sublimation ΔHsub for 13 series of organic and metal-organic compounds are considered using the correlation analysis. Each series has a fixed reaction center and variable substituents. It is shown for the first time that ΔHsub values depend not only on the classical inductive, resonance, and steric effects, but also on the polarization effect of substituents. In some series, the polarization effect has a major influence on ΔHsub.
