The technique of X-ray crystallography is used for finding the atomic (gives energy to atoms and then to molecules) and molecular structure (The arrangement of chemical bonds between atoms in a molecule). The crystals will then cause the X-ray to beam a pattern onto a film structure. Then finally you're left with a diffraction pattern (passing through a narrow aperture (film) or across an edge, typically accompanied by interference between the wave forms produced).
X-ray crystallography is a technique used for determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions.
