Abstract:The microwave spectrum of teflic acid (\chem{TeF_5OH}) in the range of \mbox{3 to 25\,GHz} was analyzed. Though teflic acid is an asymmetric top in its equilibrium structure, it behaves like a symmetric top because of the OH group internal rotation. The strongest transitions in the spectrum originate from the \chem{^{130}TeF_5OH}, \chem{^{128}TeF_5OH} and \chem{^{126}TeF_5OH} species as shown in the figure below. The \chem{TeF_5{}^{18}OH}, \chem{TeF_5OD} and \chem{TeF_5{}^{18}OD} isotopologues were also analyzed. From the rotational constants of the different istopologues and with help of quantum chemical calculations a semi empirical equilibrium structure of teflic acid was determined. The \mbox{Te-O} equilibrium bondlength was determined with accuracy to the hundredth of an angstrom. \mbox{} \begin{wrapfigure}[0]{r}[-90pt]{0pt} \includegraphics[scale=0.70]{Transition.eps} \end{wrapfigure} \vspace{1.5in} \mbox{}
