WebX-ray crystallography is an experimental technique that exploits the fact that X-rays are diffracted by crystals. It is not an imaging technique. X-rays have the proper wavelength (in the Ångström range, ~10 -8 cm) to be scattered by the electron cloud of an atom of comparable size. Based on the diffraction pattern obtained from X-ray ... DEFINITION • CRYSTALLOGRAPHY is simply a fancy word meaning "the study of crystals" • The study of crystalline solids and the principles that govern their growth, external shape, and internal structure • Crystallography is easily divided into 3 sections - - geometrical, physical, and chemical.
