The role of volume scattering in reducing spectral contrast of reststrahlen bands in spectra of powdered mineralsThe first high-resolution quantitative directional hemispherical reflectance spectra of minerals were obtained for different particle sizes, and were used to develop an accurate prediction of the particles' spectral emissivity, using Kirchhoff's law (Nicodemus, 1965) and to interpret the nature and causes of changes in the spectral contrast of reststrahlen bands. It was found that the reststrahlen bands change in shape as well as intensity; this is explained by the occurrence of substantial volume scattering at fine particle sizes. The implication of this finding for remote sensing of the earth, moon, Mercury, Mars, and the asteroids is discussed.
