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 weak or non-conventional hydrogen bond has been subject of intense scrutiny over recent years in several fields, in particular in structural chemistry, structural biology, and also in the pharmaceutical sciences. There is today a large body of experimental and theoretical evidenceconfirming that hydrogen bonds like C-H...O, N-H...pi, C-H...pi and even bonds like O-H...metal play distinctive roles in molecular recognition, guiding molecular association, and in determining molecular and supramolecular architectures. The relevant compound classes include organometalliccomplexes, organic and bio-organic systems, and also DNA and proteins. The book provides a comprehensive assessment of this interaction type, and is of interest to all those interested in structural and supramolecular science, including fields as crystal engineering and drug design.

Book Description
"This interdisciplinary book unites comprehensive considerations of the physics of non-covalent interactions with the specificity of their biochemical application in protein sciences, succeeding where pure physics and biochemical textbooks have failed. This second edition includes new chapters on intrinsically disordered proteins, microcalorimetry of proteins, cold denaturation, thermodynamic stability and thermal adaptability of proteins"--

Book Description
Chemistry 2e is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning. The second edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Substantial improvements have been made in the figures, illustrations, and example exercises that support the text narrative. Changes made in Chemistry 2e are described in the preface to help instructors transition to the second edition.

Book Description
The accurate determination of the structure of molecular systems provides information about the consequences of weak interactions both within and between molecules. These consequences impact the properties of the materials and the behaviour in interactions with other substances. The book presents modern experimental and computational techniques for the determination of molecular structure. It also highlights applications ranging from the simplest molecules to DNA and industrially significant materials. Readership: Graduate students and researchers in structural chemistry, computational chemistry, molecular spectroscopy, crystallography, supramolecular chemistry, solid state chemistry and physics, and materials science.

Book Description
Noncovalent interactions often provide the spine of biomolecular and material structures, and can therefore play a key role in biological and catalytic processes. Selectivity in chemical reactions, particularly in catalytic processes, is often an orchestral action of various noncovalent interactions occurring in intermediates and transition states. Although the role of hydrogen bonding is well explored in catalysis, the other types of weak interactions, namely cation–π, anion–π, π–π stacking, pseudo-agostic, halogen, chalcogen, pnictogen, tetrel and icosagen bonds, must also be considered. Naturally, the chemo-, regio- or stereoselectivity of a reaction depends on the stability of such noncovalent-interaction-supported species in catalytic systems. Therefore, an in-depth understanding of these weak interactions may be the key to designing new catalytic materials. Providing an overview of the role of these different types of noncovalent interactions in both homogenous and heterogeneous catalysis, this book is a valuable resource for synthetic chemists who are interested in exploring and further developing noncovalent-interaction-assisted synthesis and catalysis.
