Diffuse Reflectance Spectroscopy - an overview ...

Diffuse reflectance spectroscopy is a versatile tool that allows us to accurately measure the flux per wavelength of light reflected in a scattered manner from a sample. Whether the sample be almost purely diffuse, as in a lightly packed powder, predominately specular, as in a burnished metal surface, or something in between, such as a glossy paint sample, diffuse reflectance spectroscopy tells much .

Diffusion - Wikipedia

Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential) as a result of random motion of the molecules or atoms. Diffusion is driven by a gradient in chemical potential of the diffusing species.
