Study of alpha-parallel and alpha-perpendicular of cholesteryl nonanoate molecule

摘要

Up to now only the trace and the components $alpha$-1$/, $alpha$-2$/ of polarizability tensor of liquid crystal sample have been investigated. The new method of $alpha$- $PLL$/ and $alpha$-$PRP calculation of cholesteryl nonanoate molecule was described in this work. It was determined the $alpha$-$PLL$/ and $alpha$-$PRP$/ were nonlinear functions of the temperature. It proves that cholesteryl nonanoate molecule changes its conformation. Besides, the values are always constant in all mesophase temperatures and the value of ($alpha$-1$/-$alpha$-2$/)$Delta@n must be also independent on the temperature.
