摘要：

The chemisorption of C2H2, C2H4 on Ni and Pd films deposited at room temperature was investigated by means of infrared reflection spectroscopy. At room temperature, acetylene and ethylene are chemisorbed in a C2V structure with the C-C bonds parallel to the metal surface. The hybridization change of the carbon atoms from sp toward sp2 with acetylene chemisorption and from sp2 toward sp3 with ethylene chemisorption seems to occur at room temperature. A strange feature of the spectra was an abnormally low C-H stretching frequency, which will be discussed. © 1979.
