摘要：

The mid-infrared spectrum of the ionic complex He-NH4+ has been recorded in the vicinity of the triply degenerate nu(3) (t(2)) vibration of the free ammonium ion. Apart from a small blue shift (approximate to 0.7 cm(-1)), the spectrum of the complex closely resembles that of the monomer. Ab initio calculations predict a vertex-bound minimum structure with an intermolecular well depth D-e approximate to 150 cm(-1), a center-of-mass separation of R(e) approximate to 3.17 Angstrom and barriers for internal rotation less than 30 cm(-1).
