Gallium arsenide cluster ions were generated by laser vaporization in a supersonic nozzle, trapped in a Fourier transform ion-cyclotron resonance mass spectrometer, and allowed to react with NH_3 forming addition complexes with the cluster cations. With excess NH_3, Ga_xAs_y(NH_3)^+_z with the same GaAs composition (x+y) was observed with several values of z. This observation of different numbers of chemisorbed NH_3 molecules at completion is explained in terms of the existence of multiple isomers of positive GaAs clusters. Negative Ga_xAs^−_y clusters were found to be inert toward NH_3.
