The solutions say transitions B and C are allowed. Does anyone know why we can neglect the rule about delta(m_j)=-1,0+1? I don't see any way to deduce the value of m_j values.
Also if anyone could clarify what is meant by the small "l" and big "L" rules for the electric dipole that would be great. I'm guessing big L is for the sum of spin across several atoms.
