This book provides a complete exposition of the theory of nuclear magnetic relaxation caused by the thermal motion of the molecule containing the relaxing nucleus. The author begins by defining the physical quantities encountered in nuclear magnetic resonance studies and surveying pioneering investigations in the field. Nuclear magnetic relaxation by scalar, dipolar, quadrupolar and spin-rotational interactions and by anisotropic chemical shift are then examined in detail. Relaxation rates are expressed in terms of spectral densities, and the values of the spectral densities for various molecular shapes are calculated by random walk or Brownian motion dynamics. The text should be within the grasp of readers who have taken undergraduate courses in electromagnetic theory and in classical and quantum mechanics, although topics in these fields of particular relevance are to be found in appendices. This book will be of value to postgraduate students and research workers using n.m.r. in physics and physical chemistry departments, and by scientists in industrial and medical research.

Liquids --- Relaxation phenomena. --- Nuclear magnetic resonance. --- Random walks (Mathematics) --- Diffusion processes. --- Magnetic properties. --- Random walks (Mathematics).

The subject of stability problems for viscoelastic solids and elements of structures, with which this book is concerned, has been the focus of attention in the past three decades. This has been due to the wide inculcation of viscoelastic materials, especially polymers and plastics, in industry. Up-to-date studies in viscoelasticity are published partially in purely mathematical journals, partially in merely applied ones, and as a consequence, they remain unknown to many interested specialists. Stability in Viscoelasticity fills the gap between engineers and mathematicians and converges theore

Conjugated polymers are attractive from the viewpoint of possible applications as novel nonlinear optical materials and conductive materials. They are also very important as a group of materials of one dimensionality. The progress of research in this field is very rapid. At the present stage it is extremely useful to have review articles giving information on the most recent progress.Relaxation in Polymers contains state-of-the-art reviews on: ultrafast responses in various conjugated polymers with large optical nonlinearity; ultrafast relaxation in polysilanes; electronic properties of polysi
