“…(levels in green) parts of the Figure. The strongest of these sub-bands, Π(1 1 ) -Σ(0 0 ) was also observed and rotationally analysed in 14 NH 3 -Kr [211] and 15 NH 3 -Ar [212]. The closeness of this main sub-band in the molecular complex to the r R(0,0) transition in ν 1 + ν 3 in the monomer suggests that the equivalent, ν 1 + ν 3 vibrational excitation is involved in the dimer.…”

The literature on the high-resolution spectroscopic investigation of molecular complexes containing small polyatomic species excited in their vibrational overtones is reviewed. They turn out to be complexes containing acetylene, ammonia and water, mainly excited in their 2CH, 2NH and 2OH vibrations, respectively. The majority of results published on these systems was obtained using an instrumental set-up based on cw-cavity ring-down spectroscopy, built in the 'Laboratoire de Chimie quantique et Photophysique' at the 'Université libre de Bruxelles' (CQP/ULB) and named FANTASIO+, which is described. It allowed retrieving upper state vibrational predissociation lifetimes, which are highlighted together with more results. The sequence of experiments at CQP/ULB prior and along the line of those supporting the investigation of molecular complexes is briefly illustrated.

“…Except for a short report in the MIR [228], there was no previous investigation of the ammonia-RG complexes in the IR range. The assignment of the observed sub-bands in the 2NH range turned out to be quite challenging [201,211,212]. It was assumed that the level structure in the 2NH state was similar to that in the GS.…”
