Nuclear Magnetic Resonance Shift Reagents


Book Description

Nuclear Magnetic Shift Reagents presents the proceedings of the Symposium on the Chemistry of Nuclear Magnetic Resonance Shift Reagents, held in Dallas, Texas, on April 9–11, 1973. This book discusses the fundamental aspects of shift reagent chemistry as well as the physical and chemical properties of shift reagents. Comprised of 16 chapters, this compilation of papers starts with an overview of the deuterium isotope effect in lanthanide shifts. This text then examines the variations in coordination geometries for chemically equivalent molecules of shift reagent-substrate complexes in the solid state, which illustrate the ease with which changes occur in the coordination sphere of lanthanide complexes. Other chapters discuss the dipolar nature of proton resonance shifts in lanthanide shift reagent systems. This book considers as well the feasibility of using chiral shift reagents. The final chapter deals with the effects of chemical equilibrium and adduct stoichiometry in studies of shift reagent. Chemists, biochemists, and molecular physicists will find this book useful.

Bibliography of Magnetic Materials and Tabulation of Magnetic Transition Temperatures


Book Description

This referenced compilation of magnetic transition temperatures represents (with the Addendum) papers actually received by the RMIC through May 1972 and consists of two lists (alphabetical by compounds), one for Curie and one for Neel temperatures. Where different values appeared in the literature for a single compound, all are listed with sepa rate references given for each. There is no attempt at critical evaluation, which, except for a few welt-studied and well characterized materials, would hardly be worth the effort. All that one can say for most of the compounds is that for a given material with a certain (or all too often uncertain) history of preparati'on and treatment, stoichiometry, homoge neity, and chemical or structural purity a magnetic transition was indicated at the temperature(s) listed. Only when the reasons for different values are explicitly stated in the literature do they appear as brief comments in the body of the lists. In order to include the most recent data, and to eliminate the delay involved in recomposition of the lists, an addendum is provided. While this requires the perusal of two lists rather than one, it does ensure that the compilation represents the entire RMIC collection at the moment of going to press. The 2478 references are restricted to those papers specifying a Curie or Neel temperature and do not reflect the complete magnetics literature even for the materials listed.







Handbook on the Physics and Chemistry of Rare Earths


Book Description

Handbook on the Physics and Chemistry of Rare Earths: Including Actinides, Volume 53, is a continuous series covering all aspects of rare earth science, including chemistry, life sciences, materials science and physics. The book focuses on rare earth elements [Sc, Y, and the lanthanides (La through Lu], but when relevant, information is included on the related actinide elements. Individual chapters are comprehensive, up-to-date, critical reviews written by highly experienced, invited experts, with this release including chapters on a Comparison of the Electronic Properties of Lanthanides with Formally Isoelectronic Actinides, Redox catalysis with redox-inactive rare-earth ions in artificial photosynthesis, and more. The series, which was started in 1978 by Professor Karl A. Gschneidner Jr., combines, and integrates, both the fundamentals and applications of these elements with two published volumes each year. - Presents up-to-date overviews and new developments in the field of rare earths, covering both their physics and chemistry - Contains Individual chapters that are comprehensive and broad, with critical reviews - Provides contributions from highly experienced, invited experts
