Modern Charge-Density Analysis focuses on state-of-the-art methods and applications of electron-density analysis. It is a field traditionally associated with understanding chemical bonding and the electrostatic properties of matter. Recently, it has also been related to predictions of properties and responses of materials (having an organic, inorganic or hybrid nature as in modern materials and bio-science, and used for functional devices or biomaterials). The first part of the book includes theoretical and methodological chapters which provide a wide ranging and up-to-date overview of the physics behind charge-density distribution and the most advanced methods to model and interpret it (from theory or experiment). In the second part, applications in several fields are presented ranging from Biomacromolecules to Energetic Materials. The effects of external stress (e.g. produced by temperature, pressure or photo-excitation) and the resultant electron-density response are analyzed. Implications for chemistry, biology and material science are described with an outlook on future developments. The ever-growing impact of charge-density analysis on modern fields of research including supramolecular chemistry, crystal engineering, complex magnetic materials, molecular reactivity and recognition is strongly featured. Modern Charge-Density Analysis is inherently multidisciplinary and written for chemists, physicists, crystallographers, material scientists, and biochemists alike. It serves as a useful tool for scientists already working in the field by providing them with a unified view of the multifaceted charge-density world. Additionally, this volume facilitates the understanding of scientists and PhD students planning to enter the field by acquainting them with the most significant and promising developments in this arena.
