[SOLVED] QM: Spin -orbit coupling: Solve [(L.S), L]
Griffiths problem 6.16
Solve the following commutators (he lists a bunch but i can't get even the first one)
(a) [(L.S) , L]
(b) [(L.S) , S]
(c) [(L.S) , L^2]
there's a few more, but i think if i get the idea then i can do the rest. I know it isn't supposed to be hard but for some reason i can't get it.
Thank you any help you can give.
