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.
