Abstract Surface tension of nematic liquid crystals (LC) was measured by the Wilhelmy plate and ring methods. A possibility to estimate surface tension of individual LC and their mixtures basing on the minimum information (molecular structure) was demonstrated. The group-contribution scheme basing on the parachor was suggested.
