Category RESTR_EQUAL_TORSION

Name:
'RESTR_EQUAL_TORSION'

Parent category:
CIF_RSTR

Definition:

   

      Items in this category list the atoms defining the
      torsion angles that are restrained to be equal in
      the final refinement. The torsion angle is the dihedral
      angle between the plane defined by atoms 1, 2 and 3, and
      the plane defined by atoms 2, 3 and 4.


Category is of type Loop
