WebFourier-transform infrared (FTIR) spectroscopy is a widely used technique for investigating materials in the gaseous, liquid, or solid phase. It is based on the interaction between electromagnetic radiation and natural vibrations of the chemical bonds among atoms that compose the matter. 5 FTIR can detect the stretching vibrations of carbon ... The reflectance of the surface of a material is its effectiveness in reflecting radiant energy. It is the fraction of incident electromagnetic power that is reflected at the boundary. Reflectance is a component of the response of the electronic structure of the material to the electromagnetic field of light, and is in … Zobraziť viac Hemispherical reflectance The hemispherical reflectance of a surface, denoted R, is defined as Spectral hemispherical reflectance The spectral hemispherical reflectance in frequency and … Zobraziť viac Reflection occurs when light moves from a medium with one index of refraction into a second medium with a different index of refraction.

Reflectivity is the square of the magnitude of the Fresnel reflection coefficient, which is the ratio of the reflected to incident electric field; as such the … Zobraziť viac Given that reflectance is a directional property, most surfaces can be divided into those that give specular reflection and those that give diffuse reflection. For specular … Zobraziť viac The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency.
