MICROCRYSTALLINE REFLECTIVITY IN UNIAXIAL CRYSTALS
MetadataShow full item record
Publisher:Ohio State University
The infrared reflectivity of a uniaxial microcrystalline powder is described as a composite reflectivity from various faces which have the proper alignment with respect to the incident beam. The optical constants of the microcrystal are assumed to be the bulk crystal values and the various faces presented to the incident beam are obtained from a simple rotational averaging. The Fresnel reflection coefficients for an absorbing uniaxial crystal are given for an arbitrary orientation of the optic axis with respect to the plane of incidence. Applications to experimental data are discussed.
