摘要：

Infrared spectra of mass selected NH4+-Ar-n (n = 1-7) cluster ions have been recorded in the range between 3000 and 3500 cm(-1) by means of photodissociation spectroscopy. Vibrational assignments are based on ab initio calculations by taking into account complexation-induced frequency shifts and splittings as well as band intensities. The results indicate that the first four Ar atoms occupy equivalent vertex-bound sites, while further Ar atoms are probably located at the faces of the tetrahedral monomer.
