High Resolution FTIR Spectroscopy of Trisulfane Hsssh: a Candidate for Detecting Parity Violation in Chiral Molecules
Abstract
The measurement of the parity violating energy difference Δ_{pv}{E} between the enantiomers of chiral molecules is among the major current challenges in high resolution spectroscopy and physical-chemical stereochemistry. Theoretical predictions have recently identified dithiine^{b} and trisulfane as suitable candidates for such experiments. We report the first successful high-resolution analyses of the Fourier transform infrared (FTIR) spectra of trisulfane. A band centered at 861.0292 cm^{-1} can be assigned unambiguously to the chiral trans conformer by means of ground state combination differences in comparison with known pure rotational spectra. A second band near 864.698 cm^{-1} is tentatively assigned to the cis conformer by comparison with theory.
