Infrared Optical Constants from Pressed Pellets of Powders: I. Improved n and k Values of (NH₄)₂SO₄ from Single-Angle Reflectance

In combination with other parameters, the real, n([Formula: see text]), and imaginary, k([Formula: see text]), components of the complex refractive index, [Formula: see text] = n + i k, can be used to simulate the optical properties of a material in different forms, e.g., its infrared spectra. Ultimately, such n/k values can be used to generate a database of synthetic reflectance spectra for the different morphologies to which experimental data...
