Abstract
Data for the temperature dependence of the pretilt angles for nematic liquid crystal mixtures on a polyimide surface are compared with diffe rent theories. It is found that our recently proposed population distr ibution model can explain all the observations well, when we assume a Boltzmann distribution between the different states. The only exceptio n is one sample with azoxybenzenes, which undergo chemical changes.
