The first EXAFS results on nebulized solutions are presented. High quality spectra from in situ X-ray absorption experiments are performed on micrometer-sized spheres of nickel (II) bromide in 95% alcoholic or in aqueous solution via ultrasonic nebulization. The structural information given by the X-ray absorption complete the data given by other absorption spectroscopies. The strong dissociation of the precursors is shown and the first coordination sphere of the nickel atom is evidenced. It is formed by nickel atoms surrounded by hydrating water molecules.
