The chemical
structure of 4-cyano-4′-pentyl-biphenyl, arrangement of rod-like molecules in
the (nonchiral) nematic phase (N), and temperature dependence of the ordinary
refractive index no (effective for light that is linearly polarized
with its electric field perpendicular to the director n), the
extraordinary refractive index ne (effective for light that is
linearly polarized with its electric field parallel to the director n),
and the isotropic refractive index .
