Book Description
The present volume deals with the application of the following techniques; computational chemistry, X-ray diffraction, and two-dimensional nuclear magnetic resonance. The book will discuss how these methods can be used to study steric aspects of biomolecular interactions.

Book Description
Weak chemical interactions, i.e., hydrogen and halogen bonds, underlie the formation of molecular crystals and control their structure. This book provides a description of the properties and characteristics of these interactions, as well as conclusions about their nature, made from measurements of the vibrational (Raman) spectra of a large number of compounds in the temperature range 5 K – 300 K. The diagnostic parameters of hydrogen bonds, i.e., vibration frequency, Raman intensity, band half-width and degree of anharmonicity, are described in detail, for the entire range of bonds, from weak to ultrashort, intra- and intermolecular. The results of the study of vibrational spectra of halogen-halogen bonds are also presented, which allow us to draw a certain conclusion about its nature. The book will appeal to students and scientists whose interests lie in the field of research of chemical compounds, and biological and pharmaceutics systems.

Book Description
The study of gases, clusters, liquids, and solids as units or systems, eventually focuses on the properties of these systems as governed by interactions between atoms, molecules, and radicals that are not covalently bonded to one another. The stereo/spatial properties of molecular species themselves are similarly controlled, with such interactions found throughout biological, polymeric, and cluster systems and are a central feature of chemical reactions. Nevertheless, these interactions are poorly described and characterized, with efforts to do so, usually based on a particular quantum or even classical mechanical procedure, obscuring the fundamental nature of the interactions in the process. Intra- and Intermolecular Interactions Between Noncovalently Bonded Species addresses this issue directly, defining the nature of the interactions and discussing how they should and should not be described. It reviews both theoretical developments and experimental procedures in order to explore interactions between nonbonded entities in such a fundamental manner as to elucidate their nature and origins. Drawing attention to the extensive experience of its editor and team of expert authors, Intra- and Intermolecular Interactions Between Noncovalently Bonded Species is an indispensable guide to the foundational knowledge, latest advances, most pressing challenges, and future directions for all those whose work is influenced by these interactions. - Comprehensively describes the nature of interactions between nonbonded species in biological systems, liquids, crystals, clusters, and in particular, water. - Combines fundamental, theoretical, background information based on various approximations with the knowledge of experimental techniques. - Outlines interactions clearly and consistently with a particular focus on frequency and time-resolved spectroscopies as applied to these interactions.

Book Description
Prof. Baev presents in his book the development of the thermodynamic theory of specific intermolecular interactions for a wide spectrum of organic compounds: ethers, ketones, alcohols, carboxylic acids, and hydrocarbons. The fundamentals of an unconventional approach to the theory of H-bonding and specific interactions are formulated based on a concept of pentacoordinate carbon atoms. New types of hydrogen bonds and specific interactions are substantiated and on the basis of the developed methodology their energies are determined. The system of interconnected quantitative characteristics of the stability of specific intermolecular interactions is presented. The laws of their transformations are discussed and summarized. The new concept of the extra stabilizing effect of isomeric methyl groups on the structure and stability of organic molecules is introduced and the destabilization action on specific interactions is outlined.
