The study shows how the formalism induced by the minimum mean deviation from statistical equilibrium may be effectively applied to more complex atoms to obtain trial wave functions compatible with a shell picture of the atom. The objective is not only to recover the experimental value of the ground-

โฆ Synopsis
xpressions are derived for matrix elements of Et he Hamiltonian operator for spin-coupled wave functions in molecular systems having an even number of electrons. Orthogonality of spatial orbitals is not assumed, and the coupling scheme can be specified at will. Relations to other methods are noted briefly.

Anfklytic self-consistent field wave functions have been obhined for the t~it~o~-me~ stcuns in tbeir ground-state configurstions. The atomic orbit& &we bean expanded in terms of linear combinations of orbit.& from basis sets of 10 and IS Hater-type functions.
The use of hierarchical orthogonality restrictions in handling the nonorthogonality problem which arises when spin-coupled wave functions are employed to describe the electronic structure of extended molecules is investigated.
