Nuclear Magnetic Resonance Probes of Molecular Dynamics describes the theoretical basis and experimental techniques that make modern NMR spectroscopy a powerful and flexible tool for probing molecular dynamics in chemical, physical, and biochemical systems. Individual chapters, written by leaders in the development and application of NMR from around the world, treat systems that range from synthetic polymers, liquid crystals, and catalysts to proteins and oligonucleotides and techniques that include deuterium NMR, magic angle spinning, multidimensional spectroscopy, and magnetic resonance imaging. A combination of elementary and advanced material makes the book a useful introduction to the field for students at the graduate level as well as an important reference for practising NMR spectroscopists.

Despite considerable variability within the scientific community, allosteric regulation can best be defined functionally as how a macromolecule binds one ligand differently when a second ligand is or is not pre-bound to the macromolecule, which constitutes a vital aspect of protein structure/function. In Allostery: Methods and Protocols, expert researchers in the field provide key techniques to investigate this biological phenomenon. Focusing on heterotropic systems with some coverage of homotropic systems, this volume covers the monitoring of allosteric function, allosteric conformational changes, and allosteric changes in protein dynamics/sub-population distribution, as well as topics such as macromolecular and ligand engineering of allosteric functions and computational aids in the study of allostery. Written in the highly successful Methods in Molecular BiologyTM series format, the chapters include the kind of detailed description and implementation advice that is crucial for getting optimal results in the laboratory. Thorough and intuitive, Allostery: Methods and Protocols aids scientists in continuing to study ligand-induced, through-protein effects on protein function (ligand binding/catalysis), a phenomenon that is well recognized through the history of the life sciences and very poorly understood at the molecular level.

Liquid-crystalline phases are now known to be formed by an ever growing range of quite diverse materials, these include those of low molecular weight as well as the novel liquid-crystalline polymers, such phases can also be induced by the addition of a solvent to amphiphilic systems leading to lyotropic liquid crystals. Irrespective of the structure of the constituent molecules these numerous liquid-cl)'Stailine phases are characterised by their long range orientational order. In addition certain phases exhibit elements of long range positional order. Our understanding, both experimental and theoretical, at the molecular level of the static behaviour of these fascinating and important materials is now well advanced. In contrast the influence of the long range order; both orientational and positional, on the molecular dynamics in liquid Cl)'Stais is less well understood. In an attempt to address this situation a NATO Advanced Study Institute devoted to liquid ctystal dynamics was held at n Ciocco, Barga, Italy in September 1989. This brought together experimentalists and theoreticians concerned with the various dynamical processes occurring in all liquid crystals. The skills of the participants was impressively wide ranging; they spanned the experimental techniques used in the study of molecular dynamics, the nature of the systems investigated and the theoretical models employed to understand the results. While much was learnt it was also recognised that much more needed to be done in order to advance our understanding of molecular dynamics in liquid Cl)'Stais.

This book is based on a NATO Advanced Study Institute held to enhance our understanding, at both an experimental and a theoretical level, of the molecular dynamics in liquid crystals. The lecturers at the Institute, each leaders in their respective fields, have contributed chapters to the book with the aim of producing, for the first time, a coherent, pedagogical account of this interdisciplinary subject. The range of materials considered is wide, including lyotropic and thermotropic liquid crystals, biological membranes and polymeric systems. The formalism needed to characterise the rotational, translational and conformational dynamics is developed. Then the use of experimental techniques to investigate the dynamics is described; these techniques include NMR and ESR spectroscopy, neutron scattering, dielectric relaxation, infrared spectroscopy and fluorescence depolarisation. Some of these experiments are influenced by the collective orientations or director modes which are also considered. The results of these experiments are presented and the theory necessary to understand them is described, with particular attention being paid to the influence of the long range liquid--crystalline order on the dynamics.
