CP-FTMW spectrum of bromoperfluoroacetone

The microwave spectrum of the molecule bromoperfluoroacetone has been measured on a CP-FTMW spectrometer in the 6-18. The spectra is dense with approximately one transition every 5 MHz on average. Rotational constants, centrifugal distortion parameters, and nuclear quadrupole coupling constants will be discussed. Comparisons to the previously studied halogen analogues perfluoroacetone\footnote{J.-U. Grabow, N. Heineking, and W. Stahl, \textit{Z. Naturforsch.} \textbf{46a} (1991) 229.} and chloroperfluoroacetone\footnote{G. Kadiwar, C. T. Dewberry, G. S. Grubbs II and S. A. Cooke, Talk \textbf{RH11}, 65$^{\mathrm{th}}$ International Symposium on Molecular Spectroscopy (2010).} along with a family of previously studied halogenated acetone species will be discussed
