It has been proved that the localization energies of alternant hydrocarbons correlate linearly with cosines of the angle of total pi-electron energies of the corresponding sigma-complexes in chemical reactions. Topologically variable upper and lower bounds for the topological form of the localization energy are obtained. It has been shown that among the various sigma-complexes of the same compound, the one having the highest a(4) coefficient is more likely to form.
