Sublimation Energy of Benzene

Abstract

Using a free‐electron model for the π‐electron system in benzene the electronic quadrupole moment has been calculated to be 26.29 × 10⁻²⁶ esu which is in fair agreement with the experimental value of 34.86 × 10⁻²⁶ esu. Considering the molecular interaction to be quadrupolar in origin for benzene crystal the sublimation energy was calculated to be 10.64 kcal/mole which is in good agreement with the experimental value of 10.67 kcal/mole.
