_geom_torsion.angle

Definition:

   
    Angle defined by the listed sites and accompanying symmetry operation codes.
    The torsion-angle definition should be that of Klyne and Prelog.
    The vector direction _geom_torsion.atom_site_label_2 to
    _geom_torsion.atom_site_label_3 is the viewing
    direction, and the torsion angle is the angle of twist required
    to superimpose the projection of the vector between site 2 and
    site 1 onto the projection of the vector between site 3 and
    site 4. Clockwise torsions are positive, anticlockwise torsions
    are negative.
