Available in PDF, EPUB and Kindle. Book excerpt: It is well known that NMR is an excellent tool for the study of those molecular systems that are characterized by a great number of spatial configurations, high entropy and the presence of significant random movements, such as liquids, polymers and biological cellular systems. The aim of this book is to introduce some new ideas to the subject. The book is theoretical and conceptual in character. It has grown out of lectures given by the author on general physiology and the elements of biophysics, and from his lectures and seminars given at, among others, the Congresses of the European Society of NMR in Biology and Medicine. The information is presented in six chapters and follows a logical development of the subject. The probabilistic and statistical fundamentals are first introduced. The theory of spin relaxation is derived from the classical and quantum theory of linear irreversibility. Diffusion and flow are treated here with particular application to living systems such as the NMR blood flow-meters, flow imaging, the dynamics and order in water systems of plants and tumors.
