1. The problem statement, all variables and given/known data
Consider the case of an atom with two unpaired electrons, both of which are in s-orbitals. Write the full basis of angular momentum eigenstates representing the coupled and uncoupled representations

2. Relevant equations
l=r×p
lx=ypz-zpy
ly=zpx-xpz
lz=xpy-ypx

l+=lx+ily
l-=lx-ily

3. The attempt at a solution
I am not sure how to start. If I am correct I already wrote a complete basis for l.

Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

Well, the problem statement says that the electrons are in "s-orbitals". That means that the orbital angular momentum is zero. So the only relevant angular momentum is spin angular momentum, I would think.
