A Newman projection views a molecule along a chosen bond, showing substituents on the front atom and rear atom. It makes relative torsions visible without assuming that the two centres lie in the plane of a skeletal drawing.

A Newman projection is a way of visualizing the three-dimensional (3D) structure of organic molecules, particularly alkanes, in a two-dimensional (2D) format. It allows chemists to analyze the spatial arrangement of atoms and bonds around a specific bond between two carbon atoms. In a Newman projection, one looks straight down the axis of a particular bond (usually a carbon-carbon bond).
