Adsorption structure and chemical property of a sulfur-containing amino acid molecule of L-Cysteine on transition metal surface has been interested in a bio-compatibility, a bio-catalysis and a bio-materials fields. XPS (X-ray Photoelectron Spectroscopy) and NEXAFS (Near edge X-ray Absorption Fine Structure) techniques have established themselves as a powerful tool to characterize both a local molecular adsorption structure and a chemical condition of the adsorbates at adsorption sites. In the present study, we have paid attention to the isotope effect for coadsorption systems (H@sub 2@O or D@sub 2@O)/L-Cysteine/Cu(100) studied by coupling of (S2p, C1s, O1s and N1s) XPS and sulfur K-edge NEXAFS measurements. There are some dominant differences in the experimental results of XPS and NEXAFS spectra for coadsorption systems of (H@sub 2@O or D@sub 2@O)/L-Cysteine/Cu(100).
