The incident X-ray beam; n is an integer. This observation is an example of X-ray wave interference (Roentgenstrahlinterferenzen), commonly known as X-ray diffraction (XRD), and was direct evidence for the periodic atomic structure of crystals postulated for several centuries. N l =2dsinq Bragg’s Law. Multitran.com: Free online dictionary in English, German, French, Spanish. XRD analysis has a prospective use in the new drug development & the quality control of the formulations. It helps in gaining insights on the polymorphism. The main advantages of x-ray diffraction are: It is a rapid and powerful technique for identifying unknown minerals and materials It only requires preparation of a minimal sample for analysis Interpreting the resulting data is relatively straightforward XRD measurement instruments are widely.

X-ray Diffraction Techniques
9. Father and Son
Lawrence Bragg had produced a Law of X-ray diffraction that explained Von Laue's results far more satisfactorily than Von Laue's own explanations. But Bragg, who had just returned to Cambridge as a research student, had only limited resources with which to test his theory.
Lawrence Bragg presented his ideas to his father, William Henry Bragg, the Cavendish Professor of Physics at the University of Leeds. Until 1912 W.H. Bragg had believed that X-rays must be some kind of neutral particle, but von Laue's discovery had quickly convinced him that X-rays were waves. In 1913 W.H. Bragg designed and made an X-ray spectrometer that would allow many types of crystals to be investigated using his son's theory.
The collaboration between the two Braggs led many people to believe that it was the father, not the son, who had come up with 'Bragg's Law'. This distressed Lawrence Bragg, who was only 22 and trying to establish his own reputation. Although Bragg's father made every attempt to correct anyone who made this mistake, there was a lasting difficulty between the two men. A few days before his death in 1971 Lawrence wrote to his friend Max Perutz, 'I hope that there are many things your son is tremendously good at which you can't do at all, because that is the best foundation for a father-son relationship'.
