Abstract

Spectroscopic studies of van der Waals complexes make it possible to study intermolecular interactions, which play an important role in understanding the processes occurring in an interstellar medium, including molecules in the gas and condensed phases. Recent experimental studies of complexes consisting of ammonia molecule (NH₃) with Ne atoms and molecular hydrogen (H₂) are presented. In the laboratory, complexes were formed by expansion of a supersonic gas jet into vacuum. Their rotational spectra were measured using highly sensitive intracavity millimeter-wave spectrometer based on OROTRON. The influence of symmetry and nuclear spin statistics of NH₃ and H₂ on the spectra of weakly bound complexes was considered, and their excited metastable states correlating with different monomer internal rotor states were detected.
