Spin densities in the Waller–Hartree spin‐free method were found to be the same as in the spin‐projected Slater determinant method. The reduced spin projector Q is introduced and its relation with the spin projector P is discussed. An equation is obtained to show that a Sanibel coefficient can be expressed as a linear combination of N ! products of Sanibel coefficients.
