The tricritical behavior of nematic liquid crystals near the transition to an isotropic liquid has been discovered as a result of very precise measurements of the heat capacity. The assumption of the closeness of this transition to the tricritical point offers the best possibility of consistently explaining existing experiments on the heat capacity, light scattering, order parameter, and it eliminates the question of long-range action in liquid crystals.
