a,b, Measured circularly polarized and unpolarized extinction spectra of samples stacked at ±10° (a) and ±45° (b). c,d, g-factor \(g = 2\left( {Ext_{{\mathrm{LCP}}} - Ext_{{\mathrm{RCP}}}} \right)/\left( {Ext_{{\mathrm{LCP}}} + Ext_{{\mathrm{RCP}}}} \right)\) (c) and CD (d) calculated from extinction spectra of aforementioned samples. ‘a.u.’, arbitrary units.
