Abstract
Refractive indices of two nematic liquid crystals, 5CB and 5PCH, were measured from the 400- to 800-nm region at various temperatures. Resul ts fit the three-band model well. Through comparisons, the contributio ns of sigma and pi electrons to the refractive indices and birefringen ce of uniaxial liquid crystals are evaluated quantitatively. These phy sical insights are useful for tailoring liquid crystal molecules with proper refractive indices.
