A photoionization study of the Me(NH3) clusters formed in the reaction
of photoablated third group metal vapor with gaseous ammonia is reported. The
photoionization spectra exhibit some features due to vibrational excitation
of ionic clusters and to transitions to neutral Rydberg states leading to autoionization.
DFT quantum chemical calculations are performed on the Me(NH3). The
cluster geometries are fully optimized imposing the C
symmetry.
The calculated values of the IPs are in agreement with those experimentally
determined.
