Abstract
A photoionization study of the Me(NH3) clusters formed in the reaction of photoablated third group metal vapor with gaseous ammonia is repor ted. The photoionization spectra exhibit some features due to vibratio nal excitation of ionic clusters and to transitions to neutral Rydberg states leading to autoionization. DFT quantum chemical calculations a re performed on the Me(NH3). The cluster geometries are fully optimize d imposing the C-3v symmetry. The calculated values of the IPs are in agreement with those experimentally determined.
