Dynamics of Metal Centers Monitored by Nuclear Inelastic Scattering

, 2005
Nuclear inelastic scattering of synchrotron radiation has been used now since 10 years as a tool for vibrational spectroscopy. This method has turned out especially useful in case of large molecules that contain a M\"ossbauer active metal center.
