The absolute proton affinity of NH/sub 3/ (203.6 +- 1.3 kcal/mole at 298 K) and the proton solvation energies by more than one NH/sub 3/ have been determined by the molecular beam--photoionization method. In addition, the NH/sub 3//sup +/--NH/sub 3/ interaction energy (0.79 +- 0.05 eV) has been measured by photoionization of the neutral van der Waals dimer. These experiments have shown that photoionization of van der Waals clusters is a very powerful method for determining the energetics of gas phase proton solvation.
