Abstract

The order parameters of a number of different solutes dissolved in a number of different nematic liquid-crystal solvents are measured and compared. It is shown that the order parameters can all be rationalized with the ansatz that there exist two independent ordering mechanisms operating in the liquid crystals employed. With this ansatz it is possible to fit the experimental order parameters to better than 5%. This opens the possibility of the accurate prediction of order parameters in ordered liquids.

摘要

测量并比较了溶解在多种不同向列型液晶溶剂中的多种不同溶质的序参量。结果表明，所有序参量都可以用这样一种假设来合理化解释，即在所用的液晶中存在两种独立的有序化机制。基于这一假设，能够将实验序参量拟合到优于5%的精度。这为准确预测有序液体中的序参量开辟了可能性。
