Abstract

Structurally similar to previously characterized chiral tagging candidates, {\it trans}-2-fluoro-3-(trifluoromethyl)oxirane (tFTFO) is investigated, both theoretically and experimentally, as a potential chiral tagging molecule. With a strong, simple rotational spectrum, tFTFO shows promise for applications in chiral analysis through the conversion of enantiomers into spectroscopically distinct diastereomeric species through noncovalent attachment. Fourier transform microwave spectroscopy from 5.6 to 18.1 GHz is used to obtain the rotational spectrum of five isotopologues of tFTFO and four isotopologues of its heterodimer with the argon atom. Analysis of these spectra allows the determination of the structures for both species. Initial results show that the structure of the argon complex is distinct from the structures previously described for the 3,3,3-trifluoro-, 3,3-difluoro-, and 3-fluoro-1,2-epoxypropane species, suggesting that the addition of the fluorine atom to the ring carbon alters bonding in the epoxy moiety.
