Abstract

The metastable decomposition of photoionized NO/NH₃ clusters has been investigated employing a reflectron time-of-flight mass spectrometer. The metastable dissociation spectra of the most prominent cluster ion species NO⁺(NH₃)_n (3 ≤ n ≤ 28) show that the rate coefficient for the loss of one NH₃ molecule from the cluster rapidly increases up to n = 13 and thereafter is nearly independent of the cluster size. This is interpreted as evidence of a stable structure that consists of a central NO⁺ ion surrounded by a first solvation shell of 12 NH₃ molecules.
