    • For all liquid crystalline mixtures with xw > 0.09 the WAXD patterns exhibit two meridian aromatic diffuse scattering maxima corresponding to 0.34 and 0.36 nm. Both maxima are also present for the pure compound (see ref 34). The presence of both peaks also in the whole concentration range and also for pure compounds prompted us to discard the coexistence of two phases as the cause of both peaks

    • The equation was proposed for calamitic nematic liquid crystals, but it has also been used to calculate, for instance, an approximate value of the mean interhelix distance in chiral nematic phases of DNA in water in ref 45. In that case, the mesogenic element is analogous to the system presented here
