A Look at a Seires of Alkyl and Perfluoroalkyl Bromides

The pure rotational spectrum of bromoperfluoroethane between 9.0-13.0 GHz has been measured on a chirped pulse Fourier transform microwave spectrometer. A total of 839 transitions were observed for the six isotopolouges. Only the $trans$ conformer was observed for which the rotational constants are reported. Nuclear electric quadrapole coupling constants have been determined and reported. Also, two dipole forbidden/quadrapole allowed $\Delta J$ = 2 transitions were observed in the spectra.
