This textbook is designed for graduate students to introduce the basic concepts of Nuclear Magnetic Resonance spectroscopy (NMR), spectral analysis and modern developments such as multidimensional NMR, in reasonable detail and rigor. The book is self-contained, so, a unique textbook in that sense with end of chapter exercises included supported by a solution manual. Some of the advanced topics are included as Appendices for quick reference. Students of chemistry who have some exposure to mathematics and physics will benefit from this book and it will prepare them to pursue research in different branches of Chemistry or Biophysics or Structural Biology.
The determination of the three-dimensional structure of a biological molecule is the starting point in the understanding of molecular mechanisms involved in its complex biochemical reactions. The molecular architecture of multimolecular systems such as membranes and chromosomes provides the key to the fascinating field of molecular biology. Stereochemical details of biological macromolecules and their interactions with pharmacological agents form the basis for drug design. Naturally, the study of the structure and function of biological molecules has aroused tremendous interest and investigations in this area are being carried out in a large number of laboratories. The techniques used for this purpose include both experimental methods (X-ray and neutron diffraction measurements, study of NMR, ESR, vibrational and electronic spectra, ORD, CD and dipole moment measurements, biochemical modifications etc. ) and the oretical methods (quantum mechanical and classical potential energy calculations, Monte Carlo simulations and molecular graphics). F or several years now, X-ray diffraction [1] has served as our only source of infor mation on the three-dimensional arrangements of atoms in biopolymers. Fiber-diffrac tion of DNA led to the proposal of the DNA double helix. Fibers of long~hain polymers show ordering in the direction of the fibre-axis but not in the transverse plane. Accurate estimates of the dimensions of helical structures can be made using techniques on the basis of which models of biopolymers can be constructed.

All the great personages of the past, who have left an indelible mark on the trail of events in the history of mankind, become a centre around which gathers, with the passage of time, a mass of legends and myths. These, more often than not, are later assumed to be facts that cannot be verified. The historicity of many of these legends begins to be questioned then, be they related to the life of a Christ, a Buddha or a Moses. Sri Ramakrishna, the latest in the line of these Great Masters, is an exception to this historical dilemma, as he appeared just a century ago. Even today researches succeed in discovering hitherto unknown truths about him, and these can be easily verified. The author of this book published by Advaita Ashrama, a publication house of Ramakrishna Math, Belur Math, India, has brought to light some fresh findings on Sri Ramakrishna that will be extremely interesting for all his devotees and admirers.
This original version of The Gospel of Ramakrishna is based on the author M.Æs own English translation from the Bengali. A classic but until recently neglected work, it is presented here in an edited form for the contemporary reader. It is introduced with a comprehensive biography of Shrl Ramakrishna (1836-1886), written by his most famous disciple, Swami Vivekananda. Also included are several b/w photographs of Ramakrishna and his disciples. Book jacket.
