The audience for this thorough overview includes advanced undergraduates and postgraduate researchers in macromolecular sciences who can benefit from more familiarity with the use of X-ray diffraction for obtaining structural information on biological substances, natural and synthetic high polymeric materials. X-Ray Diffraction by Macromolecules comprises three parts: fundamental, experimental and analytical, and the volume as a whole may serve as an intermediate textbook to bridge the treatments found in primers and specialist works. It presents a thorough treatment of principles and applications, and gives full, practical details on experimental methods and the treatment of results, along with many examples of actual analysis.
