Electron spin echo studies of solvation structure

Abstract

The development and application of electron spin echo modulation analysis for deducing detailed geometrical information about the solvation shell structure of paramagnetic species is described. This technique makes it possible to measure weaker hyperfine interactions in disordered systems such as frozen solutions and surfaces than is normally possible. The number, distance, and orientation of first solvation shell molecules can then be determined. Applications of this technique to silver atom solvation, electron solvation, anion solvation, cation solvation, and cation solvation on surfaces are described.
