Shear modulus $C_S$ (29) and Young’s modulus $Y_{\left[110\right]}$ (6) data (line) and corresponding simultaneous fits using the nematic susceptibility ${\chi }_{B_{1g}}$ extracted from Raman scattering using Eqs. 1 and 3. Full/open symbols correspond to Raman data on SP208/MK crystal. The λ values (in relative units) used for the two crystals agree within 10%. The standard relationship between $Y_{\left[110\right]}$ and $C_S$ was used (6) (see Supporting Information for details).
