Abstract : The present work deals almost exclusively with critically evaluated Knight shift data. Quadrupole effects and relaxation time data, and NMR in ferromagnetic materials are considered with less completeness. The Knight shift, which is measured almost exclusively by the NMR technique, has far-reaching applications in solid state physics, physical metallurgy, and other areas. For instance, it is very sensitive to details of a metal's Fermi surface, and to changes in the Fermi surface caused by alloying, and thus can serve as a sensitive test of models proposed to explain the electronic structure of metals. It is also an important analytical chemical or metallurgical tool in both basic and applied studies. For example, the NMR of metals such as cesium is used for precise measurement of magnetic fields and applications of NMR to phase diagram determinations. NMR theory is reviewed in Chapters 1 through 4, data reduction techniques are discussed in Chapters 5 and 6, and metallurgical applications of NMR are described in Chapter 7. Critical evaluation methods and coverage are detailed in Chapter 8, and the evaluated Knight shifts, together with many other physical properties that have been evaluated to a lesser extent, are treated in Chapter 9. There are summarizing tables both in Chapter 9 and in the review chapters as pertinent to the text. For example, nuclear spin-lattice relaxation times and Korringa ratios for solid nontransition metals are given in Table 2.4, and pressure dependence parameters of the Knight shift for elemental metals in Table 4.1.
