Mössbauer Spectroscopy
Mössbauer spectroscopy is a spectroscopic method to detect a slight change in energy levels of an atomic through recoil-free resonant absorption and emission of gamma rays in solids. Typically, chemical shift, quadrupole splitting, and hyperfine splitting can be observed. Due to the narrow linewidth of gamma rays, Mössbauer is extremely sensitive in terms of energy resolution. In the resulting spectra, the gamma-ray intensity is plotted as a function of the source velocity. At velocities corresponding to the resonant energy levels of the sample, a fraction of the gamma rays are absorbed, resulting in a drop in the measured intensity and a corresponding dip in the spectrum. The absorbing nuclei and sample can be characterized by the number, positions, and intensities of the dips in the spectrum. Recently, some charge state and electronic configurations have been confirmed through Mössbauer spectroscopy at cryogenic temperatures.
