Manipulation and Dilution Tools for Ruling Abundant Species "NMR is dead" was the slogan heard in the late 1960s at least among physicists, until John S. Waugh and his co-workers initiated a series of new NMR experiments, which employed the coherent modulation of interactions by strong radiofrequency fields. A wealth of new phenomena was observed, which are summarized in the introduction for the convenience of the unbiased reader, whereas Section 2 collects the basic spin interactions observed in solids. Line-narrowing effects in dipolar coupled solids by the application of multiple pulse experiments are extensively discussed in Section 3. Numerous extensions of the basic Waugh, Huber, and Haeberlen experiment have been developed by different groups and have been applied to the nuclei IH, 9Be, 19F, 27Al, 31p, 63CU in solids. Application of this technique to a variety of systems is still in progress and should reveal interesting insights into weak spin interactions in solids. It was soon realized that rare spins could be used as monitors for molecular fields in the solid state; however, rare spin observation is difficult because of the small signal-to-noise ratio. Pines, Gibby, and Waugh introduced a new concept of cross-polarization, based on ideas of Hahn and co-workers, which allows the detection ofrare spins with increased sensitivity. The dynamics involved are treated in detail. Other sections merely list results obtained by the techniques described and demonstrate their usefulness in the investigation of dynamical problems in molec ular and solid state physics.

The progress in nuclear magnetic resonance (NMR) spectroscopy that took place during the last several decades is observed in both experimental capabilities and theoretical approaches to study the spectral parameters. The scope of NMR spectroscopy for studying a large series of molecular problems has notably broadened. However, at the same time, it requires specialists to fully use its potentialities. This is a notorious problem and it is reflected in the current literature where this spectroscopy is typically only used in

This chapter describes briefly chemical shifts (or nuclear magnetic shielding constants) and indirect spin–spin coupling constants. They are well known as powerful tools for studying several molecular properties which are very important in different branches of the broad field of molecular sciences. The present description is oriented to an interdisciplinary audience and therefore it is expected that it can be followed for readers without strong backgrounds either in mathematics or physics. After a short revision of basic concepts, a

Polarization propagators (PP) are powerful theoretical tools that allow carrying out a deep analysis of the electronic mechanisms underlying any molecular response property. The inner projections of the PP and contributions from localized orbitals within the PP approaches described in were developed to fully take advantage of this power of analysis for the study of NMR spectroscopic parameters. They are based on the use of localized molecular orbitals (LMOs) related to chemically intuitive concepts to decompose the mathematical expression of

Spin–spin coupling constant J provides decisive data for organic compound characterization. This electron-mediated coupling is usually taught as transmitted between covalently bonded magnetic atoms. However, this physical interaction between nuclear spins is much more complex than that with regard to chemical bonding concept. Independent experimental and theoretical studies related to small organic and organometallic species (molecular mass below 2000gmol−1) have highlighted the existence of J couplings operating via clearly nonbonded interactions and known as “through-space” couplings. Interactions of this

This chapter is devoted to the 1–3JCCs and to the factors influencing their magnitude. The experimental and calculated J data presented in the subsequent parts of the chapter are arranged with the thought of showing how hybridization, substituent electronegativity, the complex and hydrogen bond formation, and geometry of the compound bear on the JCC magnitude and which range of changes can be expected for a given type of coupling when all these effects are taken into account. The subsequent sections

Natural bond orbital and natural J-coupling methods are used for the analysis of the Fermi-contact contributions to spin–spin coupling constant (SSCC). In this way, the SSCCs are partitioned into three contributions: Lewis, delocalization, and repolarization. This partition is applied to the study of some chemical systems to explain the main electron delocalization effects on SSCCs.

The theory and quantum-chemical calculations of the spectral parameters of nuclear magnetic resonance (NMR) are well established in the case of diamagnetic, closed-shell molecules. In contrast, NMR calculations of paramagnetic, open-shell molecules (pNMR) are scarce, limited by both assumptions within the underlying theoretical background as well as the availability of computational implementations. We discuss the systematic development of pNMR theory that recently culminated in a novel, general and systematic electronic structure approach for the shielding tensor and the associated chemical

From the initial observation of proton magnetic resonance in water and in paraffin, the discipline of nuclear magnetic resonance has seen unparalleled growth as an analytical method. Modern NMR spectroscopy is a highly developed, yet still evolving, subject which finds application in chemistry, biology, medicine, materials science and geology. In this book, emphasis is on the more recently developed methods of solution-state NMR applicable to chemical research, which are chosen for their wide applicability and robustness. These have, in many

High Resolution NMR: Theory and Chemical Applications focuses on the applications of nuclear magnetic resonance (NMR), as well as chemical shifts, lattices, and couplings. The book first offers information on the theory of NMR, including nuclear spin and magnetic moment, spin lattice relaxation, line widths, saturation, quantum mechanical description of NMR, and ringing. The text then ponders on instrumentation and techniques and chemical shifts. Discussions focus on the origin of chemical shifts, reference compounds, empirical correlations of chemical shifts, modulation
