Abstract
Negative ion photoelectron spectroscopy (NIPES) involves a kinetic energy analysis of electrons which are photodetached when a mass selected beam of negative ions is crossed with a fixed frequency laser beam. The photodetachment spectra of $SeD^{-}$ displays transitions from the $X^{2}\Pi$ state of $SeO^{-}$ to both the $X^{3}\Sigma^{-}$ and $a^{1}\Delta$ states of SeO. The singlet-triplet splitting of SeO is readily observable since selection rules regarding spin do not apply in the bound to free state process of photodetachment. The electron affinity of SeO and the negative ion potential parameters of $SeD^{-}$ have been determined.
