Abstract
A canonical transformation is performed in order to eliminate the strong Coulomb interaction between sigma and pi electrons. Using a restricted basis set for the sigma—pi system, the separability problem is solved to the extent that further corrections are proportional to fluctuations of the already small energy transfer term of the pi electrons.
