X ray powder diffraction Books
by
This new edition provides an in-depth introduction to the theories and applications of the powder diffraction method for structure determination. The emphasis is placed on powder diffraction data collected using conventional x-ray sources, which remain primary tools for thousands of researchers and students in their daily experimental work. The book is divided into two parts: chapters one though fifteen give essential theoretical background, while chapters sixteen through twenty-five guide the reader through practical aspects of extracting structural information from powder data. While developed as a text to teach students, the book is also a reference for academic and industrial researchers using the powder diffraction method in their daily work. Major revisions include expanded treatment of non-crystallographic symmetry brief introductions to the total scattering analysis and non-ambient powder diffractometry basics of quantitative analysis using the Rietveld method, including determination of amorphous content addition of a difficult pseudo-symmetric indexing case expanded coverage of direct space structure solution techniques an introduction to the mechanism of constraints, restraints and rigid bodies and a new example of structure solution of a pharmaceutical compound additional problems to help in assessment of students.
