Over recent years, no other technique has grown to such importance as that of NMR spectroscopy. It is used in all branches of science where precise structural determination is required and where the nature of interactions and reactions in solution is being studied. Annual Reports on NMR Spectroscopy has established itself as a means for the specialist and non-specialist alike to become familiar with new applications of the technique in all branches of chemistry, including biochemistry and pharmaceutics. Volume 41 of Annual Reports on NMR Spectroscopy consists of four reports covering diverse areas of molecular science. The first one is Cobalt-59 NMR Spectroscopy by J.C.C. Chan and S.C.F. Au-Yeung. Following this there is an account of Advances in Theoretical and Physical Aspects of Spin-Spin Coupling Constants by R.H. Contreras, J.E. Peralta, C.G. Giribet, M.C. Ruiz de Azua and J.C. Facelli. The third contribution is by S. Dusold and A. Sebald on Dipolar Recoupling under Magic-Angle-Spinning Conditions. The final chapter relates to the Characterization of Porous Media using NMR Methods by P.J. Berrie. - Cobalt-59 NMR Spectroscopy - Advances in Theoretical and Physical Aspects of Spin-Spin Coupling Constants - Dipolar Recoupling under Magic-Angle Spinning Conditions - Characterization of Porous Media Using NMR Methods.
