Abstract
Freedericksz measurements were performed on mixtures of a nematic mesogen a nd a V-shaped molecule. The bend elastic constant was found to decrease sig nificantly with increasing concentration of the V-shaped molecule. The resu lts are discussed theoretically, taking into account the detailed structure of the molecules.
