Study of Potential Interstellar Molecules: Nuclear Quadrupole Coupling Constants of the Nitrogen Atom in Pyrrole

Abstract

The nuclear quadrupole coupling constants of the nitrogen atom in pyrrole have been redetermined by analysis of the hyperfine structure for several low J rotational transitions. The resulting values are x"" = 1'400±O'OO8 MHz and Xbb = 1·300±O·OO8 MHz. Small modifications to the previously reported rotational constants are given.
