The Ideal Gas on the Canonical Ensemble
... The first term on the r.h.s corresponds to all terms on the l.h.s for which both molecules are in the same state, the second term corresponds to the molecules being in different states. We can now see the problem. When the particles are in different state, we have counted each state twice. The state ...

You can check that, in a single electron atom, the matrix elements are nonzero only for ∆L = 2, ∆M = 0, ±1, ±2. Parity is conserved, since Dij has even parity, and spin is conserved, because Dij acts on ...
