coefficient — 1. The expression of the amount or degree of any quality possessed by a substance, or of the degree of physical or chemical change normally occurring in that substance under stated conditions. 2. The ratio or factor that relates a quantity… … Medical dictionary
Coefficient d'Angström — Exposant d Ångström L’exposant d’Ångström (parfois aussi appelé coefficient d’Angström) est le nom de l’exposant dans la formule habituellement utilisée pour décrire la dépendance de l’épaisseur optique (appelée aussi profondeur optique en… … Wikipédia en Français

Coefficient de transparence — Épaisseur optique L’épaisseur optique d une couche atmosphérique mesure le degré de transparence du milieu. Elle est définie par la fraction de rayonnement électromagnétique (ou de lumière) diffusée ou absorbée par les composants de la couche… … Wikipédia en Français
Mass attenuation coefficient — The mass attenuation coefficient is a measurement of how strongly a chemical species or substance absorbs or scatters light at a given wavelength, per unit mass. In addition to visible light, mass attenuation coefficients can be defined for other … Wikipedia
Optical window in biological tissue — The Optical window [1] (also known as therapeutic window) defines the range of wavelengths where light has its maximum depth of penetration in tissue. Within the NIR window, scattering is the most dominant light tissue interaction, and therefore… … Wikipedia
Mathematical descriptions of opacity — When an electromagnetic wave travels through a medium in which it gets absorbed (this is called an opaque or attenuating medium), it undergoes exponential decay as described by the Beer–Lambert law. However, there are many possible ways to… … Wikipedia
Molar absorptivity — The molar absorption coefficient, molar extinction coefficient, or molar absorptivity, is a measurement of how strongly a chemical species absorbs light at a given wavelength. It is an intrinsic property of the species; the actual absorbance, A,… … Wikipedia
Quantification of nucleic acids — is commonly used in molecular biology to determine the concentrations of DNA or RNA present in a mixture, as subsequent reactions or protocols using a nucleic acid sample often require particular amounts for optimum performance. There exist… … Wikipedia
Nucleic acid quantitation — In molecular biology, quantitation of nucleic acids is commonly performed to determine the average concentrations of DNA or RNA present in a mixture, as well as their purity. Reactions that use nucleic acids often require particular amounts and… … Wikipedia
Inner sphere electron transfer — Inner sphere or bonded electron transfer[1] proceeds via a covalent linkage between the two redox partners, the oxidant and the reductant. In Inner Sphere (IS) electron transfer (ET), a ligand bridges the two metal redox centers during the… … Wikipedia
