WebApr 8, 2024 · Crystallography is an advanced imaging technique. In this technique, high-energy beams or x-rays and particles can be shot through the crystal structure of a pure substance. While this does not form a visible image, the rays and particles are diffracted in particular patterns. WebX-ray crystallography is a tool used for determining the atomic and molecular structure of a crystal. The underlying principle is that the crystalline atoms cause a beam of X-rays to …
