Natta projection

The Natta projection is a way to depict molecules with complete stereochemistry in two dimensions in a skeletal formula. This concept is named after Giulio Natta. In a hydrocarbon molecule with all carbon atoms making up the backbone in a tetrahedral molecular geometry, the zigzag backbone is in the paper plane (chemical bonds depicted as solid line segments) with the substituents either sticking out of the paper toward the viewer (chemical bonds depicted as solid wedges) or away from the viewer (chemical bond depicted as dashed wedges). The Natta projection is useful for representing the tacticity of a polymer.
