The angle between two bonds sharing a common atom is known as the bond angle. The distance between the nuclei of bonded atoms is known as bond distance. The geometry of a molecule can be characterized by bond angles and distances. A chain of four bonded atoms consists of three bonds. Each group of three contiguous atoms lies in a plane. The angle between these two planes is called the dihedral or torsional angle of the two outer bonds. Another way of visualizing this angle is to view the projection of the four atoms along the line of the central bond, also known as a Newman projection. The angle between the projections of the two outer bonds is also the torsional angle (see illustration).
