- W2949405763 abstract "Ethenes (C2H4, C2D4, cis‐1,2‐C2D2H2, and trans‐1,2‐C2D2H2) isolated in xenon matrices show dramatic and reversible infrared spectral changes between 12 and 50 K; most bands broaden with increasing temperature. In the xenon matrix, the C2H4 ν7 band is unusually broad, much broader than in the argon spectrum, while the corresponding C2D4 mode remains sharp. Though sharper than C2H4 ν7, many other bands are doublets in which one peak shows different temperature dependence than the other. The C2D4 ν7 band, however, is only a singlet. Among several possible explanations for the unusual breadth, the most likely is that C2H4 ν7 couples with the xenon lattice phonon modes through the librational movement of C2H4 within the cage. The doublets are attributed to two sites with which different modes and isotopes interact to varying degrees." @default.
