Abstract
We theoretically analyze the orientation of a nematic liquid crystal c lose to an interface, by means of a semi-microscopic model, We find th at long-range van der Waals interactions, depending on the orientation of the molecules with respect to their relative position, give rise t o subsurface deformations on a molecular scale. This result is compare d with the predictions of recently proposed elastic theories.
