Abstract
Temperature surface transitions have been observed in nearly homeotrop ic samples of nematic liquid crystal. The temperature dependence of th e nematic orientation may be described by means of the elastic model r ecently proposed. From the best fit of the experimental data it is pos sible to estimate the effective splay-bend elastic constant for the co nsidered nematic liquid crystal.
