Other than water, pure bulk liquids and solids are rarely encountered in the environment, but more commonly exist as layers on various substrates, e.g. concrete, metals, glass, etc. Unlike gas-phase transmission spectra, condensed-phase reflectance s

Reflection, Scattering, and Diffraction from Surfaces VI.
The morphology, size, and media surrounding a solid material can all influence its optical properties, such as scattering, absorption, and reflection of light. While it is possible to measure the optical properties of hundreds of individual surface o
