VELOSO, Dorila Piló; SEIDL, Peter R.; MENEZES, Sonia Maria Cabral de  and  AUREMN. Comitê de Tradução. Parameters and symbols for use in Nuclear Magnetic Resonance (IUPAC recommendations 1997). Quím. Nova [online]. 1999, vol.22, n.4, pp.622-629. ISSN 0100-4042.

NMR is now frequently the technique of choice for determination of chemical structure in solution. Its uses also span structure in solids and mobility at the molecular level in all phases. The research literature 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 symbols for the same physical quantity. It is the aim of the present recommendations to provide simple check-lists that will enable such problems to be minimised in a way that is consistent with general IUPAC formulation. The area of medical NMR and imaging is not specifically addressed in these recommendations, which are principally aimed at mainstream use of NMR by chemists (of all sub-disciplines) and by many physicists, biologists, material scientists and geologists etc. working with NMR.

Keywords : Nuclear Magnetic Ressonance; NMR experimental parameters; NMR symbols and terms.
