Abstract
All the second‐order density matrix spin components for the spin‐projected Slater determinant are presented as expansions in direct products of powers of unprojected spin‐ and residual electron density matrices. Spin components of the second‐order transition density matrices between spin‐projected Slater determinants built of orthogonal orbitals are also obtained.
