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 $NO-(H2O)n1,2$ and $NO-(D2O)n=1,2$ 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 $NO-(N2O)n-1,2$.
