Abstract
The formalism of spin-adepted reduced Hamiltonians has been formulated so far on the assumption that the underlying orbital space is orthonormalized. In this paper, the formalism is generalized to the non-orthogonal case, which may be important if the basis set of atomic orbitals is used or when studying intermolecular interactions.
