Abstract

The rotational spectrum of 2-bromopyridine (ce{C5H4BrN}) was reinvestigated in the frequency range of 10-15.5 GHz by high-resolution Fourier transform microwave (FTMW) spectroscopy. The new observations of $^{14}$ce{N} hyperfine splittings in previously studied transitionsfootnote{Caminati, W.; Forti, P. textit{Chemical Physics Letters} textbf{1972}, textit{15}(3), 343–349.} belonging to both bromine isotopologues (ce{C5H4}$^{79}$ce{BrN} and ce{C5H4}$^{81}$ce{BrN}) led to improved measurements of the rotational constants and bromine nuclear quadrupole coupling constants. The full nuclear quadrupole coupling (NQC) tensor of $^{14}$ce{N} was resolved for the first time, in addition to five centrifugal distortion constants. A comparison of the two $^{14}$ce{N} NQC tensors of ce{C5H4}$^{79}$ce{BrN} and ce{C5H4}$^{81}$ce{BrN} will be presented. _x000d_ _x000d_ _x000d_
