摘要：

Ammonia isolated in Ar and N2 matrices with concentrations of 0.5, 1.1 and 4% was investigated by high resolution inelastic neutron scattering in a temperature range from 2 to 25 K. In Ar, substitutional monomeric and dimeric sites are found which are related to a three- and a one-dimensional rotor, respectively. The one-dimensional rotor transition is split due to coupling. The three-dimensional rotor is missing in the N2 matrix.
