Abstract
Heat-flow birefringence is described by a constitutive law which links the anisotropic part of the dielectric tensor with the gradient of the heat flux or the 2nd spatial derivative of the temperature field. For a gas of linear molecules, this relation is derived from transport-relaxation equations which, in turn, were obtained from the Waldmann-Snider equation. The magnitude of the heat-flow birefringence can be inferred from the Senftleben-Beenakker effect of the viscosity and of the heat conductivity. It is found to be of measurable size.
