Category RESTR_TORSION

Name:
'RESTR_TORSION'

Parent category:
CIF_RSTR

Definition:

   

      Items in this category define torsion angles that were
      restrained 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
