Abstract
The 0$-$0 bands at 10 296 and 10 491 {\AA} of the near-infrared band system $b-$X. of the SeO $molecule^{1}$ were photographed at high resolution and their rotational structure has been analyzed. The analysis shows that the bands represent the transition $bO^{+}-XO^{+}, 1$ (X being the case-c $^{3}\Sigma^{-}$ ground state of the SeO molecule). The observed isotopic shifts of the rotational lines of $^{78}{SeO}$ from those of $^{80}{SeO}$ are in agreement with the calculated values. The derived constants in $cm^{-1}$ for $^{80}{SeO}$ are as follows:[FIGURE] For the ground state, the separation $T_{e}(1^{+}) - T_{e}(1^{-}) = 0.0096 cm^{-1}$, Klein-Dunham potential curves were constructed for the $X_{1}O^{+}$ and $bO^{+}$ states as well as for the previously known $B_{1}O^{+}$ and $A^{3}\Pi_{0}$ $states^{2,3}$ of the Seo molecule.
