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.
