Abstract
\begin{wrapfigure}{r}{0pt} \includegraphics[scale=0.6]{bromopentafluoropropane.eps} \end{wrapfigure} The microwave spectrum of the molecule 3-bromo-1,1,1,2,2-pentafluoropropane has been measured on a newly constructed CP-FTMW spectrometer along with a FTMW spectrometer relocated from Oxford University to Missouri S\&T. 3-bromo-1,1,1,2,2-pentafluoropropane has been cited as a possible safer alternative for replacing CFCs as refrigerants and this is the first of a series of studies to understand the chemistry of 3-bromo-1,1,1,2,2-pentafluoropropane with other atmospheric cleaning agents. Rotational constants, centrifugal distortion parameters, and nuclear quadrupole coupling constants will be discussed. The CP-FTMW utilized in this experiment will be discussed in great detail. The new machine has been assembled to directly create and digitize up to 18 GHz signals without the need of mixing on the broadcast or detection side of the experiment allowing for the elimination of many microwave components typically needed in both CP-FTMW and FTMW experiments.
