An approach for the description of proper bond torsions can be constructed upon similar principles with this challenge being significantly simpler. Proper bond torsions, defined by a single angle, span the 1-sphere (a circle or S 1 ) and can be discretised as appropriate to a regular n-polygon. For a molecular entity featuring m proper bond torsions, the torsional configuration space is the product space (S 1 ) m . Classical conformational analyses search such product spaces. This work will be elaborated elsewhere.
