Spin signatures of exchange-coupled triplet pairs formed by singlet

This means that the pair spin eigenstates are either symmetric (singlet and quintet manifolds) or ant ...

... conditional measure µA on A defined by µA (B) = µ(A ∩ B)/µ(A). A measurable set B is T −invariant if T −1 B = B; if in addition T preserves a measure µ, then a measurable set B is said to be T − invariant (mod 0) e such if T −1 B = B (mod 0). In this case, there exist a T − invariant set B e = B (mo ...
