Dear all We have measured Zn XANES spectra within biological samples (seeds), in ambient conditions (room temperature). In order to interprete the spectra, we are searching for Zn-organic reference spectra (XANES only). Indeed, we would be interested by Zn organic compounds with sulfur and/or nitrogen and/or oxygen in the first shell of coordination. On the joined graph are plotted the experimental spectra (microspectra on seeds), compared to Zn-citrate and Zn-cysteine. Energy calibration was checked for all spectra. thanks in advance for your answers best regards Emmanuelle Emmanuelle MONTARGES-PELLETIER Chargée de Recherche CNRS LIEC Laboratoire Interdisciplinaire des Environnements Continentaux UMR 7360 CNRS Université de Lorraine 15 avenue du Charmois F-54500 Vandœuvre-lés-Nancy - France tel 33 (0)03 72 74 47 30 mob 33(0)6 31 33 10 30 ****attention changement de numéro de téléphone **** tel 33 (0)3 72 74 47 30
