## Abstract General formulas are obtained for evaluating a basic type of oneβcenter twoβelectron integral which arises in the computation of expectation values of spinβspin and spinβorbit operators over explicitly correlated wave functions. The correlation terms are assumed to be in the form of pro
We prove the integrability of the Poisson algebra of functions with compact supports of a noncompact manifold. We also determine a Lie subalgebra of vector fields which, weakly, integrate the Poisson algebra of a not necessarily compact manifold covered by an exact symplectic manifold.
To examiue the applicability of the ro =Ip -EA approximation to all-valence semi-empirical CI calculations, two simple modeIs are studied. One is the model for zr theory and the other is for alLvalence theory. It is demonstxMed that we cannot use the same twc electron repulsion integrals in the sr o
