The nuclei in the center of atoms undergoing spin crossover can serve as specta- tors which via their emitted radiation provide information about the microscopic mecha- nisms governing the process. Conventional M?ssbauer spectroscopy has proven its use- fulness in this respect. Application of nuclear resonant scattering of synchrotron radia- tion opens new possibilities in various ways: Nuclear resonant forward scattering (NFS) makes studies of very small samples, e.g., in pressure cells or as single crystals, feasible and yields results of the Lamb-M?ssbauer factors with high accuracy, while nuclear in- elastic scattering (NIS) has initiated a novel field of vibrational spectroscopy. Examples and results of these methods will be given in the following chapter.
