Web26 Sep 2024 · What is X-ray crystallography? X-ray crystallography is a scientific field concerned with revealing the structure of matter at the atomic level. The essential method involves exposing a crystallised sample of a molecule to x-rays, usually with an instrument called an x-ray camera. WebA crystal is a homogeneous body which has been bounded by smooth plane faces. Crystals usually possess certain elements of symmetry which may be categorized into three groups: planes of symmetry, axes of symmetry and centre of symmetry. The plane of symmetry of a crystal divides it into two parts each of which is similar to the other.
