We investigated the rotational spectra of six isotopologues of pyridine-Ne2, formed by combinations of two isotopes of the nitrogen atom (14N and 15N) in pyridine with two isotopes of the rare gas atoms (20Ne and 22Ne), by using pulsed jet Fourier transform microwave spectroscopy. We detected the C2v symmetry conformer, denoted as [1,1], where the Ne atoms are located one on each side of the ring plane. The [2,0] species, with the two Ne atoms on the same side of the ring, was not observed. Two structural parameters, R and ?, that localize the rare gas atoms with respect to pyridine have been determined. The 14N nuclear quadrupole coupling constants have been obtained for the isotopologues containing this nucleus.

Abstract
We investigated the rotational spectra of six isotopologues of pyridine-Ne2, formed by combinations of two isotopes of the nitrogen atom (14N and 15N) in pyridine with two isotopes of the rare gas atoms (20Ne and 22Ne), by using pulsed jet Fourier transform microwave spectroscopy. We detected the C2v symmetry conformer, denoted as [1,1], where the Ne atoms are located one on each side of the ring plane. The [2,0] species, with the two Ne atoms on the same side of the ring, was not observed. Two structural parameters, R and ?, that localize the rare gas atoms with respect to pyridine have been determined. The 14N nuclear quadrupole coupling constants have been obtained for the isotopologues containing this nucleus.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
