Direct visualization of the H-Xe bond in xenon hydrides: Xenon isotopic shift in the IR spectra

IR spectra of xenon hydrides (HXeCCH, HXeCC, and HXeH) obtained from different xenon isotopes ( X 129 e and X 136 e ) exhibit a small but detectable and reproducible isotopic shift in the absorptions assigned to H-Xe stretching (by 0.17 - 0.38   cm − 1 ). To our knowledge, it is the first direct exp...

Zusammenfassung:IR spectra of xenon hydrides (HXeCCH, HXeCC, and HXeH) obtained from different xenon isotopes ( X 129 e and X 136 e ) exhibit a small but detectable and reproducible isotopic shift in the absorptions assigned to H-Xe stretching (by 0.17 - 0.38   cm − 1 ). To our knowledge, it is the first direct experimental evidence for the H-Xe bond in HXeY type compounds. The shift magnitude is in good agreement with quantum-chemical calculations.
