We report on the results of ellipsometric measurements of refractive indices and their dispersion over the wavelength range 500 nm-1100 nm on a single-crystal thin film of 2-methyl-4-nitroaniline (MNA). The refractive indices show large anisotropy attributable to the orientation of the molecular dipole moment.
