Abstract:The measurement of the parity violating energy difference $Delta$$_{pv}$emph{E} between the enantiomers of chiral molecules is among the major current challenges in high resolution spectroscopy and physical-chemical stereochemistry.footnote{M. Quack , textit{Fundamental Symmetries and Symmetry Violations from High-resolution Spectroscopy}, textit{Handbook of High Resolution Spectroscopy, M. Quack and F. Merkt eds.},John Wiley & Sons Ltd, Chichester, New York, 2001, vol. 1, ch. 18, pp. 659-722.}$_{'}$footnote {S. Albert, I. Bolotova, Z. Chen, C. F'{a}bri, L. Horn'{y}, M. Quack, G. Seyfang and D. Zindel, textit{Phys.Chem.Chem.Phys.}textbf{18}, 21976-21993 (2016).} Theoretical predictions have recently identified dithiine$^{b}$ and trisulfanefootnote {C. F'{a}bri, L. Horn'{y} and M. Quack, textit{ChemPhysChem}textbf{16}, 3584-3589 (2015).} 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 emph{trans} conformer by means of ground state combination differences in comparison with known pure rotational spectra. footnote {M. Liedtke, K. M. T. Yamada, G. Winnewisser and J. Hahn, textit{J.Mol.Struct.}textbf{413}, 265-270 (1997).} A second band near 864.698 cm$^{-1}$ is tentatively assigned to the emph{cis} conformer by comparison with theory.
