On a class of approximate formulas for total -electron energy of benzenoid hydrocarbons
Abstract: The method for obtaining approximate formulas of the (n, m)-type for the total -electron energy of benzenoid hydrocarbons (communicated in J. Serb. Chem. Soc. 54 (1989) 189) is simplified and extended so as to include arbitrary spectral moments. The accuracy of the formulas thus obtained is very good and these need no additional fitting by means of empirically determined parameters
