Optimal Gaussian-type orbital GTO basis sets of positron and electron in positron-molecule complexes are proposed by using the full variational treatment of Ε½ . molecular orbital FVMO method.

The eigenblock equation for a Fockian-or Huckel-type Hamiltonian matrix of a molecule being an alternative form of the Brillouin theorem and determining Ε½ . the noncanonical molecular orbitals NCMOs was generalized to the case of nonorthogonal initial basis sets.

Molecular orbital calculations were carried out for the dimerization step in the polymerization process of vinyl acetate and styrene through free radicals and ionic mechanisms. The calculations were performed for monomers, dimers, their positive and negative ions, and free radicals. The minimum-ener
