Bond and inner shell interaction coefficients for hydrocarbons

Molecular interactions may be broken up into the interaction of bonds and inner shells. Results for bond and inner shell interaction coefficients for pairwise additive termsC₆,C₈,C₁₀ andd₄ are given, as well as the non-(pairwise) additive coefficient ₃. Simple combination rules may be used to estimate these terms with good results. Parameters should be applicable to macromolecules.
