Infrared spectroscopy has been used to analyze the microstructures of liquid‐crystalline polymers in various mesophases. It was quite evident that there is little indication of conformational order associated with the flexible polymethylene sequences in the nematic or isotropic phases. However, additional spectroscopic evidence does suggest that polyesters with an even number of methylene units have a higher degree of lateral order when compared to those with an odd number in the liquid‐crystalline state.
