a(4)Many factors influence van Edward force: molecular size, spatial configuration of molecules, molecular charge distribution. [translate] aH2O is polar molecule ,and O2 is non-polar molecule. [translate] aTherefore ,H2O is larger than O2 in the magnitude of intermolecular forces. [translate] ...
The intermolecular forces between benzene molecules and between ammonia molecules are computed in a semi-empirical manner. The long-range attractive forces are calculated from optical dispersion data and dipole moments, and the short-range repulsive forces are estimated from second virial coefficients. ...

Group theory shows that the effects of assuming centrosymmetry may be significant in the [$\zeta \zeta 0$] or $\Sigma $ direction. Assuming that the replacement of deuterium by hydrogen does not change the intermolecular forces, the frequency distribution of function and the heat capacity of ...
