The literature pertinent to the Mössbauer effect has been briefly reviewed, particularly with regard to the observation of surface effects by Mössbauer spectroscopy. The theoretical background to the discovery of the Mössbauer effect is discussed together with a detailed description of the nuclear hyperfine interactions, isomer shift, quadrupole coupling and magnetic hyperfine splitting. The temperature dependence of the recoil free fraction is derived for some model lattices as is the average energy transfer to the lattice. The relative Intensities of hyperfine split lines is discussed in some detail. The experimental techniques used for observation of the effect are reviewed briefly and a thorough description given of the spectrometer used in the work. Some description of the theory of operation of this spectrometer is also given. The materials used in the experimental work included zeolites containing iron, ferrous sulphides, iron supported on silica and ferric oxide, these materials are described fully and the spectra obtained illustrated. The spectra are interpreted particularly with regard to the solid state properties of the materials.
