Abstract
High resolution analysis has been completed on the LaO $C^{2}\Pi\rightarrow{A}^{\prime}{^{2}\Delta}$ and $C^{2}\Pi\rightarrow{X}^{2}\Sigma^{+}$ electronic transitions. The $C^{2}\Pi$ state exhibits a large $n$-doubling and the ${X}^{2}\Sigma^{+}$ state has a hyperfine spliting due to the inteaction of the La nuclear spin with the unpaired electron. A total of seven elcetronic states of LaO have now been characterized. A model of the electronic structure is applied to calculate the approximate energies of the unobserved $^\Delta$ states of ScO and YO. Good agreement is obtained between the model calculations and the experimental results for the LaO $A^{\prime}{^{2}\Delta}$ electronic state.
