title: Local electronic structure of functional groups in glycine as anion, zwitterion, and cation in aqueous solution.
abstract: Nitrogen and oxygen K emission spectra of glycine in the form of anions, zwitterions, and cations in aqueous solution are presented. It is shown that protonation has a dramatic influence on the local electronic structure and that the functional groups give a distinct spectral fingerprint.
