Newman projection
The Newman projection, which was introduced by Melvin Spencer Newman is one of several ways to represent a molecule as two-dimensional three-dimensional structure. In this process the resulting molecule along a selected single bond is considered.
Use
The Newman projection is suitable for the representation of the conformation of a molecule. One differentiates between different conformers of alkanes, also rotamers by their torsion angles. It is also suitable for the description of reaction mechanisms and the prediction of the stereochemistry of a reaction product, for example by the Cram's rule.

- Fischer projection
- Wedge -dash notation
