Mossbauer spectra of liquid solutions fixed as submicroscopic (nanosize) droplets in solid carriers were taken at room temperature and 77 K. A porous silicate (“thirsty glass”) and microemulsions prepared with a paraffin/naphthalene mixture as dispersion medium served as carriers. Solutions of Mossbauer-active tin(IV) and iron(II) complexes were incorporated in these carriers as nanosize droplets. The Mossbauer effect was observed at temperatures above the freezing point of the solutions. For comparison, the systems were also studied in frozen state.
