Sažetak

The results of a preceding paper which describes the CI
method in the second quantization are used to construct basis
vectors in the case of singly and doubly excited configurations
for molecules and radicals. The matrix elements of the Hamiltonian
are also given. A method for calculating the electronic
density distribution in the CI method is formulated. An analog of
the well known Brillouin theorem for radicals is obtained.
