CO on Pt ( 335 ) : Electric field screening on a stepped surface


We compare CO’s response to electric fields at edge and terrace sites on the stepped Pt~335! surface. The comparison is made at zero frequency and at the frequency of the C–O stretch vibration. Atop-bonded CO is observed with reflection–absorption ir spectroscopy ~RAIRS!, electroreflectance vibrational spectroscopy ~EVS!, and high-resolution electron energy… (More)
