Magnetic Resonance Studies of the Heterogeneous Rotational and Translational dynamics in Disordered Materials
The long-established method of distinguishing between heterogeneous and homogeneous line shapes was introduced in the seminal paper by Bloembergen et al. . The differentiation between the two types of spectral lines is based on whether one can alter the shape or just the amplitude of a line by an external perturbation. This concept has been applied many times particularly in optical hole burning spectroscopy where the distribution of transition frequencies can often be traced back to structural inhomogeneities in the material under study. It is well known that the frequency of an electronic transition, for example, sensitively depends on the local symmetry. This technique has been successfully applied to the structural elucidation of glasses .
