Abstract

• There have been few core level photoemission studies of amino acids in the gas phase , due to the low target densities which can be achieved. However core level binding energies are needed to interpret the spectra of adsorbed molecules, and to verify electronic structure calculations. Using synchrotron radiation (SR), we have measured photoemission spectra of all core levels of glycine, methionine and proline. The SR valence spectra are in good agreement with published He I and II spectra, and the glycine core level spectra are in good agreement with [1]. The proline and methionine spectra extend the range of data available, and allow a discussion of the systematics of the core binding energies. The oxygen core level energies of the carboxylic acid group vary by <0.4 eV, and most of the N 1s energies fall in a range of 0.3 eV, in spite of the different chemical state of nitrogen in proline (an imino rather than amino group). Proline contains only one nitrogen atom, but the N 1s spectrum shows two peaks.We assign this to the existence of at least two conformers in the gas phase and confirm this result by comparison with theoretical calculations. Thus, structural information can be obtained by XPS for complex biomolecules, as has been done for ethanol. (literal)
