Category Description

               Data items in the CHEM_COMP_ANGLE category record details about
               angles in a chemical component. Angles are designated by three
               atoms, with the second atom forming the vertex of the angle.
               Target values may be specified as angles in degrees, as a
               distance between the first and third atoms, or both.
