High-resolution electron spectroscopy of different adsorption states of ethylene on Pd(111)
The adsorption of ethylene at 100 K on clean and oxygen precovered Pd(1 1 1) surfaces and the thermal evolution of the ethylene adsorbate layers have been investigated experimentally by high-resolution electron energy loss spectroscopy (HREELS), high-resolution X-ray photoelectron spectroscopy with synchrotron radiation, thermal desorption spectroscopy and theoretically by ab initio density functi
