An aromatic noble-gas hydride: C₆H₅CCXeH.

ABSTRACT: We report on the aromatic noble-gas hydride, C₆H₅CCXeH, identified in a xenon matrix using infrared spectroscopy and extensive quantum chemical calculations. This molecule is prepared by 250-nm photolysis of phenylacetylene (C₆H₅CCH) isolated in a xenon matrix and subsequent thermal mobilization of hydrogen atoms at about 40 K. The characteristic H-Xe stretching mode of C₆H₅CCXeH is observed at about 1500 cm^-1, and a number of other fundamentals also appear in the experimental spectra. The assignment is supported by deuteration experiments providing predictable shifts of the vibrational frequencies. The experimental and calculated spectra are in a good agreement. C₆H₅CCXeH is computationally
