Critical review of analytical applications of Mössbauer spectroscopy
illustrated by mineralogical and geological examples (IUPAC Technical
S. Nagy, and A. Vértes
Abstract: We have developed a new terminology for Mössbauer
pattern analysis in order to enhance the performance of qualitative
analysis by Mössbauer spectroscopy. In this approach, Mössbauer
parameters are considered as a function of a number of externally adjusted
experimental parameters at which the spectrum has been recorded. The
basis of analytical classification is the microenvironment, which is
determined by an assembly of atoms causing the same hyperfine interactions
at one particular class of the Mössbauer probe atoms.Since Mössbauer
spectroscopy measures hyperfine interactions very sensitively, the microenvironment
presents itself as a fundamental concept for analytical purposes. Our
approach can also help to systematize the Mössbauer data for the
identification of individual physicochemical species from the corresponding
patterns present in the spectrum.
