Nuclear spin relaxation in liquids and gases

The review covers the progress in the field of NMR relaxation in fluids during the period from June 2013 through May 2014. The emphasis is on comparatively simple liquids and solutions of physico-chemical and chemical interest, in analogy with the previous periods, but selected biophysics-related topics and relaxation-related work on more complex systems (macromolecular solutions, liquid crystalline systems, glassy and porous materials) are also covered. The first part of the chapter is concerned with general, physical and experimental aspects of nuclear spin relaxation, while the second part is concentrated on applications.
