The rotational spectrum of the morpholine-H2O complex was measured and assigned using a Balle-Flygare type FT microwave spectrometer. Rotational, quartic centrifugal distortion, and 14N quadrupole coupling constants were determined, and a N ellipsis H-O hydrogen-bonded structure was found to be cons

✦ Synopsis
The rotational spectra of 1,2,4-trifluorobenzene, its six 13 C isotopic species, and its argon van der Waals complex were recorded using a molecular beam FT microwave spectrometer. The 13 C r s coordinates of the monomer and the structure of the complex were derived. The argon atom was found to be located 3.517 A ˚above the ring plane.
