A circle with three bonds from the centre and three from the rim.
Also known as: Newman diagram, Sawhorse alternative, Circle with six bonds, Conformational projection
A Newman projection looks straight down a bond: the front atom is the circle's centre and the back atom is the circle itself. It exists to show the torsion angle between the two ends, which is the one thing a skeletal drawing cannot express.
Denotes a view along a specified bond, with the near atom at the centre of a circle and the far atom at its circumference.
Contexts: Laboratory
Is drawn specifically to display the torsion angle between front and rear substituents, which no other common projection shows.
Contexts: Laboratory
Distinguishes staggered from eclipsed conformations, the energy difference between them being what conformational analysis measures.
Contexts: Laboratory
A circle with three lines radiating from its centre and three more from its circumference, at angles between them.
