The equatorial conformer of pyrrolidine has been discovered while investigating the rotational free jet spectrum of the pyrrolidine-water adduct. It is more stable than the axial species, previously assigned with conventional microwave spectroscopy (W. Caminati, H. Oberhammer, G.

โฆ Synopsis
All three possible conformers of resorcinol have been observed in the free-jet millimeter wave spectrum (60-78 GHz). Estimates of the conformational energy differences and of the torsional barrier of the hydroxyl groups are given.

The free jet absorption millimeter-wave spectrum of methylthioglycolate-SD has been investigated in the 60-78 GHz frequency range. The double-minimum potential associated with the SD group torsion generates a vibrational spacing D 01 ร 8285(5) MHz between the O / and O 0 states of the A sublevel. Th
A free jet millimeter wave spectrometer has been modified in order to observe the rotational spectra of van der Waals molecular complexes. Here the free jet millimeter wave spectrum of the pyridine-argon molecular complex, as investigated in the 60-78 GHz frequency range, is reported.
