Abstract

Hydrated nitric oxide anions may well play an important role in the ion-molecule. chemistry of the ionosphere. We have recently recorded the photoelectron (photodetachment) spectra of $NO^{-}(H_{2}O)_{n_1,2}$ and $NO^{-}(D_{2}O)_{n=1,2}$ using 2.540 ev photons. Relative to the photoelectron spectrum of unclustered NO**, these spectra are shifted to lower electron kinetic energies and are heavily broadened. The solvation interaction in hydrated nitric oxide anions will be discussed and compared with other anion-molecule complexes previously studied in our lab including several nitric oxide anion-containing species such as $NO^{-}(Ar), NO^{-}(Kr), NO^{-}(Xe)$. and $NO^{-}(N_{2}O)_{n-1,2}$.
