Values of Frank’s elastic constant K1 for 5CB as a function of temperature. In the nematic phase (red squares) the values were obtained from Bunning et al.30 using magneto-optic techniques to study the Fréedericksz transition. The values of rotational elasticity L in the isotropic phase (black circles) of 5CB-\(\mathrm{\alpha }\) d2 were obtained from the NMR data analysis. The inset figure shows the coherence length as a function of temperature and the model fitting curve \({\upxi }_{H}=A/\sqrt{T-{T}_{c}^{*}}+{\upxi }_{\infty }\).
