a, A one-dimensional chain of TATA+ molecules with fixed 20.6 Å spacing and a variable angle, θ, between the transition dipole \(\mathop{{\rm{\mu }}}\limits^{ \rightharpoonup }\) (red) and vector connecting TATA+ centers (blue). b, Rotational strength vs. number of TATAs in the one-dimensional chain for TATA+ molecules rotated 10° clockwise (θ = 100°, red) or 10° counterclockwise (θ = 80°, blue) away from perpendicular. c, Periodic variation of dissymmetry factor as the angle between the intermolecular vector and transition dipole vector changes. The simulated dissymmetry factor corresponding to the experimental θ is indicated in pink.
