Answer

a. This transition is forbidden, because $\Delta \mathcal{l}=0$. b. This transition is allowed, because $\Delta \mathcal{l}=-1$. c. This transition is forbidden, because $\Delta \mathcal{l}=0$. d. This transition is forbidden, because $\Delta \mathcal{l}=-2$. e. This transition is allowed, because $\Delta \mathcal{l}=+1$.

Work Step by Step

On page 814, the selection rule tells us that for allowed transitions, $\Delta \mathcal{l}=\pm 1$.
