The Uσ-space distortion set {Cσ,
Fσ, Aσ} for formally achiral and chiral
molecules
The construction of the stress tensor trajectories
Tσ(s), however, involves the required additional
symmetry breaking in the form of the e3σeigenvector, making it possible to distinguish the CCW and CW
preferences for the torsional C1-C2 BCP . The presence of
non-overlapping Tσ(s ) for the CCW and CW torsions
for both the C1-N7 BCP and the C1-C2 BCP demonstrates the
uniqueness of the Tσ(s ) of the CCW and CW
torsions.
The CCW and CW stress tensor trajectories Tσ(s )
of the C1-N7 BCP show significant differences by visual
inspection, where the form of the CCW Tσ(s )
indicates a more helical morphology than is the case for the CW
Tσ(s ). In contrast, the CCW and CW
Tσ(s ) of the C1-C2 BCP appear, by visual
inspection, to display near mirror symmetry between the CCW and CW
components. It can also be seen, on the same scale, that the
Tσ(s ) of the (dominant) torsional C1-N7BCP is larger than that of the torsional C1-C2 BCP .
