dc.description.abstractUnlike hydrocarbons, fluorocarbons are helical in their all-trans most stable conformations. A definitive experimental determination of the helical angle has not been accomplished because single crystal X-ray studies are not available due to the lack of suitable crystallization solvents, but a value of $17^{irc}$ from exactly trans is generally accepted from X-ray fiber studies. Using a pulsed-jet Fourier Transform microwave spectrometer, we have observed and assigned the rotational spectra of the lowest energy all-anti C$_2$ symmetry form of perfluoro-n-pentane and all three of its $^{13}$C isotopomers. A, B, and C values of the parent species are 990.6394(4) MHz, 314.00020(14) MHz, and 304.37034(14) MHz, respectively. A range of effective r$_0$ structures incorporating various model constraints are consistent with about $16^{irc}$ torsion and a Kraitchman analysis of the parent and $^{13}$C species gives $13.3^{irc}$. Ab initio calculations are consistent with the experimental results.en_US
