Microwave spectrum of [1,1]-pyridine-Ne2.
We investigated the rotational spectra of six isotopologues of pyridine--Ne(2), formed by combinations of two isotopes of the nitrogen atom ((14)N and (15)N) in pyridine with two isotopes of the rare gas atoms ((20)Ne and (22)Ne), by using pulsed jet Fourier transform microwave spectroscopy. We detected the C(2v) 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 theta, that localize the rare gas atoms with respect to pyridine have been determined. The (14)N nuclear quadrupole coupling constants have been obtained for the isotopologues containing this nucleus.
