Possible values of total angular momentum of a 2 electron system

Click For Summary
The discussion centers on determining the possible values of total angular momentum for a two-electron system. The total spin values are confirmed to be 1 and 0, with the total angular momentum in the z-direction ranging from 1 to -1. The relationship between total spin (S) and magnetic quantum number (m) is clarified, where S=1 corresponds to m values of 1, 0, and -1, while S=0 corresponds to m=0. Participants confirm that the initial confusion is resolved, leading to a correct understanding of the angular momentum values. Overall, the thread concludes with an affirmation of the correct interpretation of the angular momentum values.

Hey,

Also a bit confused on this one, the question is displayed below

The possible total spin values are 1,0,-1 and I know that

\mid l-s\mid\leq j\leq l+s\: ,\: -j\leq m_{z}\leq j

Where the latter inequality is in integer steps, so I'm not really sure if it is as simple as substituting in the 's' values into the first inequality and then using the maximum 'j' value in the second inequality.

Probably didn't make any sense.

Any help is appreciated!

Hmm actually is it that the total spin can be either 1 or 0, and the total angular momentum in the z-direction can be 1,0,-1.

So S=1 goes to m=1,0,-1 and S=0 goes to m=0?

Or is that wrong...

Cheers,
SK

This is the correct answer. Very good!
