X-Ray Crystallography and Diffraction

X-Ray Crystallography and Diffraction. Instructor: Prof. Ranjit Kumar Ray, Department of Materials Science and Engineering, IIEST Shibpur. The properties of any crystalline material are very much functions of its crystal structure and internal arrangement of atoms. X-ray diffraction is an elegant method to determine crystal structure and related parameters. This course provides a glimpse of how X-ray diffraction can be used to solve various crystallographic problems of both single and polycrystalline materials, starting from an elementary level.
