- Wedge-hash (or wedge-dash) diagrams are used to show the 3D shape of molecules12. They are ideally suited to showing the structure of sp 3 hybridised (tetrahedral atoms)1. Wedge projection is a stereochemical projection, roughly in the mean plane of the molecule, in which bonds are represented by open wedges, tapering off from the nearer atom to the farther atom and is mainly used to illustrate the conformation of larger cycloalkanes3. The wedge and dash notation is used to represent three-dimensional structures of molecules using a two-dimensional surface, like a sheet of paper or a computer screen2.
