Molar absorptivity, also referred to as molar extinction coefficient, is a measure of the flexibility of a substance to soak up gentle at a selected wavelength. It’s outlined because the absorbance of an answer containing 1 mole of the substance per liter of answer, with a path size of 1 centimeter. The SI unit of molar absorptivity is m2/mol.
Molar absorptivity is a crucial parameter in lots of areas of science, together with analytical chemistry, biochemistry, and spectroscopy. It’s used to find out the focus of a substance in an answer, to establish and characterize compounds, and to review the interactions between molecules.
