The former author has shown by experimentation in paraazoxyanisol that there is a phenomenon of orientation of liquid crystals perpendicular to the direction of the temperature gradient if no convection is present. The interpretation made is that the orientation is caused by the scattering of elastic waves which predominate in the direction of the temperature gradient. Obviously such an experiment requires more complete verification. This the second author has done by photographing the entire diffraction ring produced by the liquid crystal group and by showing that the distribution of the density of the film is in accord with preceding experiments and interpretation.
