Preferred Label : spin projection;
IUPAC definition : A component, M S, of the angular spin moment S along an arbitrary axis (usually chosen
as the z-direction). M S can take the values between -S and S: -S, -S 1,..., S-
1, S. The term is also used to denote an operation (spin-symmetry projection) allowing
one to eliminate spin contamination in the cases where wavefunctions are not eigenfunctions
of the operator S 2.;
