The linear elastic stiffness tensor of the crystalline organic semiconductor, rubrene, is measured using Brillouin light scattering spectroscopy and computed from first-principles van der Waals density functional theory calculations. Here, the results are compared with recent measurements of in-plane reduced elastic constants c¯22, c¯33, and c¯23 determined through anisotropic buckling experiments.
