Names:'_geom_torsion_max' '_geom_torsion_min' '_geom_torsion_av'
Definition:
Maximum, minimum and average torsion angles in degrees bounded by the four atom sites identified by the _geom_torsion_atom_site_label_ codes. These must match labels specified as _atom_site_label in the atom list. The torsion- angle definition should be that of Klyne and Prelog (1960). Ref: Klyne, W. & Prelog, V. (1960). Experientia, 16, 521-523.
