摘要：
We determined the order parameters of nematic liquid crystals by using infrared linear dichroism measurements. The infrared band utilized in this study was due to the carbon-carbon in plane stretching vibration of the benzene ring at 1600 similar to 1500 cm(-1). The validity of the method was confirmed by comparing the results with those from two different modes, the C = N stretching mode and the pi --> pi* transition mode.
