Abstract

We have derived the real and imaginary indices of refraction for 10 phyllosilicate minerals-montmorillonite, beidellite, nontronite, hectorite, saponite, illite, illite-smectite (60/40 interlayered) kaolinite, halloysite, and serpentine-from 100-2000 cm^-1 (5-100 μm) at 2 cm^-1 spectral sampling using classical Lorentz-Lorenz dispersion theory. We present the real and imaginary indices and the oscillator parameters with which they were modeled. Use of these optical constants will aid in the modeling of thermal infrared spectra of planets, asteroids, interplanetary and interstellar dust, and protoplanetary disks around nearby stars.
