If the initial and final states belong to $A_1$ and $B_1$ irreducible representation respectively, the allowed electronic transition from $A_1$ to $B_1$ is:
| $\mathrm{C}_{2}$, | E | $\mathrm{C}_{2}$ | $\sigma$, | $\sigma_{v}$ | |
|---|---|---|---|---|---|
| $\mathrm{A}_{1}$ | 1 | 1 | 1 | 1 | z |
| $\mathrm{A}_{2}$ | 1 | 1 | -1 | -1 | 1 |
| $\mathrm{B}_{1}$ | 1 | -1 | 1 | -1 | x |
