Electronic structure of saturated hydrocarbons in the semiempirical equivalent orbital method

The problem of matrix elements of the Hartree-Fock Hamiltonian for saturated hydrocarbons in the EO method is considered. It is stated, that all the proposed scales of such parameters are incomplete or lead to an incorrect band structure of diamond. It is shown that the data on the band structure of diamond may be useful to obtain the full scale of the parameters for the calculations of the electronic structure of hydrocarbons.
