Hello.
The quantum mechanics textbook shows the relation of J1 + J2 + J3 ≠ J1 + (J2 + J3). I believe Ji is total angular momentum operator for ith group of electrons (but actually I have not seen J1 operator while I have seen J12 operator so far).
I don't know how to prove J1 + J2 + J3 ≠ J1 + (J2 + J3). I think this play essential role of explaining why there are many coupling schemes.
Please help me to do this:)
