(a) Average absorption levels (dashed for Left CP and straight for Right CP) for periodic triple turn helices aligned with LP = 700 nm, and featuring a central line described by the equations in (4), with VP = 300 ± 10 nm, WD = 110 ± 10 nm, ED = 300 ± 20 nm, θ 0 = 6π*(0.9 ± 0.06), p = 10 ± 0.7. (b) Corresponding CDA spectrum as defined in (3); {A, B, C, D} indicate the CD A values measured by means of the PA technique, while O indicates the AO crossing point.
