PARAMETERS AND SYMBOLS FOR USE IN NUCLEAR-MAGNETIC-RESONANCE

NMR is now frequently the technique of choice for the determination of chemical structure in solution. Its uses also span structure in solid s and mobility at the molecular level in all phases. The research lite rature in the subject is vast and ever-increasing, Unfortunately, many articles de, not contain sufficient information for experiments to be repeated elsewhere, and there are many variations in the usage of sym bols for the same physical quantity. It is the aim of the present reco mmendations to provide simple check-lists that will enable such proble ms to be minimised in a way that is consistent with general IUPAC form ulation. The area of medical NMR and imaging Is not specifically addre ssed in these recommendations, which are principally aimed al the main stream use of NMR by chemists (of all sub-disciplines) and by many phy sicists, biologists, materials scientists and geologists etc. working with NMR. The document presents recommended notation for use in journa l publications involving a significant contribution of nuclear magneti c resonance (NMR) spectroscopy. The recommendations are in two parts: A. Experimental parameters which should be listed so that the work in question can be repeated elsewhere. B. A list of symbols (using Roman or Greek characters) to be used for quantities relevant to NMR.
