WebThe Beer-Lambert Law is. A= ϵbC A = ϵ b C, where A is the absorbance (a unitless quantity), ϵ ϵ is the molar absorptivity in M−1 ⋅cm−1 M − 1 ⋅ c m − 1, b is the length of the light ... WebMolar absorptivity is a term used in chemistry to measure how a particular chemical absorbs light at a particular wavelength. It is also known as molar extinction coefficient denoted by ‘ε’. This property can be calculated by using the Beer – Lambert Law. The intrinsic property of the chemical known as absorbance A is measured using the ...
