Chemical Applications of Mössbauer Spectroscopy

subject

description

The Tutorial Lecture begins with a brief recapitulation of the hyperfine interactions and the relevant parameters observable in a Mossbauer spectrum. The main chapter with selected examples of chemical applications of Mossbauer spectroscopy follows and is subdivided into sections on: basic information on structure and bonding; switchable molecules (thermal spin transition in mono- and oligonuclear coordination compounds, light-induced spin transition, nuclear-decay-induced spin transition, spin transition in metallomesogens); mixed-valency in biferrocenes and other iron coordination compounds, and in an europium intermetallic compound; electron transfer in Prussian blue-analog complexes; molecule-based magnetism; industrial chemical problems like corrosion; application of a portable miniaturized Mossbauer spectrometer for applications outside the laboratory and in space. The Lecture ends with concluding remarks and an outlook to future developments.
