Oxygen K-edge X-ray absorption near edge structures (XANES) of sublimated films of amino acids

Oxygen K-edge X-ray absorption near edge structures (XANES) spectra of amino acids (glycine, L-α-alanine, β-alanine, L-serine, L-asparic acid and L-tyrosine) were measured. Several peaks of XANES spectra were successfully assigned on the basis of DV-Xα calculation.
