## Ε½ . The traces of the p-order reduced density matrices p-RDM split into independent Λ†2 Δ‰ontributions associated to the subsets of p-electron eigenstates of the S and S z operators. Here, we report the partial traces for the blocks of the low-order RDMs corresponding to pure spin states of an N-

## Abstract For arbitrary __k__, the separation of spin variables is performed in the reduced density matrix of the __k__th order (RDM‐__k__) on the basis of the Fock coordinate function method. The independent spatial components of RDM‐__k__ are analyzed. For RDM‐__k__ of the total spin eigenstate
