Abstract
The microwave spectrum of a carbon-13 isotope of cis-1,2-difluorocyclopropane,$^{\ast} CHFCHFCH_{2}$, has been assigned in natural abundance. The normal and deuterium isotopic rotational constants reported $previously^{1}$ were combined with the carbon-13 data to partially determine the molecular structure. The $r_{s}$ parameters are $r(C_{1}C_{2}) = 1.488(3){\AA}$ and $r(C_{1},{_{2}}H) = 1.093(4){\AA}$. These structural parameters will be compared to the trans isomer of 1,2-difluorocyclopropane as well as to related geometrical pairs of fluorinated three-membered rings. The results will also be discussed in terms of recent theoretical studies of these ring systems.
