The anchoring energy of a nematic liquid crystal can be evaluated from measurements of the tilt angle at the boundary of its substrate. The equilibrium between surface and elastic energies determines the geometric structure of the distortion. For an obliquely evaporated SiO film, the energy value is about 10-3 erg/cm2.
