Abstract

The microwave spectra of the following carbon-13 isotopes of trans-1,2-difluorocyclopropane have been assigned in natural abundance: $^{\ast}CHFCHFCH_{2}, CHFCHF^{\ast}CH_{2}, ^{\ast} CHFCHFCD_{2}$ and $CHFCHF^{\ast}CD_{2}$. Combination of these data with the normal and deuterium isotopic assignments reported $previously^{1}$ provides sufficient rotational constants to determine the molecular structure. The partial Kraitchman parameters are: [FIGURE] These experimental parameters are compared to theoretical geometries and predictions of the influence of fluorine substituents upon bonding in three-membered rings.
