Question: Let us consider a two-electron system like helium where L-S coupling is significant.Explain why the transition from parahelium to orthohelium, and vice versa, are not expected to be observed. Show that the L=1 state of the system is a triplet. Write the respective spectroscopic terms for the triplet.
