PARAMETERS AND SYMBOLS FOR USE IN NUCLEAR-MAGNETIC-RESONANCE (IUPAC RECOMMENDATIONS 1997) (REPRINTED FROM PURE-APPL-CHEM, VOL 69, PG 2489, 1997)

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 do not contain sufficient information for experiments to be repeated elsewhere, and there are many variations in the usage of symb ols for the same physical quantity. It is the aim of the present recom mendations to provide simple check-lists that will enable such problem s to be minimised in a way that is consistent with general IUPAC formu lation. The area of medical NMR and imaging is not specifically addres sed in these recommendations, which are principally aimed at the mains tream use of NMR by chemists (of all sub-disciplines) and by many phys icists, biologists, materials scientists and geologists etc. working w ith NMR. The document presents recommended notation for use in journal publications involving a significant contribution of nuclear magnetic resonance (NMR) spectroscopy. The recommendations are in two parts: ( 1) Experimental parameters which should be Listed so that the work in question can be repeated elsewhere. (2) A list of symbols (using Roman or Greek characters) to be used for quantities relevant to NMR. (C) 1 998 IUPAC. Published by Elsevier Science B.V.
