http://www.swissmodel.expasy.org/course/text/chapter1.htm WebThe component atoms that determine phi and psi. Phi involves the four atoms on the left; psi involves the four atoms on the right. The planes for phi and psi both share two atoms with the reference plane. This allows phi and psi (and dihedral angles in general) to be specified by just four points.
