Polarized infrared absorption spectrum of an optically anisotropic crystal was formulated under Fourier transform polarized infrared microspectroscopy. The formulation of the spectrum requests us to set the optically anisotropic crystal at its extinction position under an IR polarizing microscope. Under this experimental constraint, pleochroic distribution of absorbance due to OH dipoles was also formulated for the purpose of determining the orientation of the OH dipole in an optically anisotropic crystal. The formulation was applied to determine the orientations of the OH dipoles in topaz and quartz. The OH dipoles in topaz predominantly lies in the (010) plane and inclined 27° from the c-axis. The OH dipoles in quartz lie almost perpendicular to the c-axis.
