WebApr 11, 2024 · For determining the Beer Lambert law equation, let’s combine equation (2) & (4), and take the log of these, we get: l o g ( I o I t) = k’k’’bc…. (5) We can express equation …
WebBeer's law (sometimes called the Beer-Lambert law) states that the absorbance is proportional to the path length, b, through the sample and the concentration of the absorbing species, c: A α b · c The proportionality constant is sometimes given the symbol a, giving Beer's law an alphabetic look: A = a · b · c This law is also applied to describe the attenuation of solar or stellar radiation as it travels through the atmosphere. In this case, there is scattering of radiation as well as absorption. The optical depth for a slant path is τ′ = mτ, where τ refers to a vertical path, m is called the relative airmass, and for a plane-parallel atmosphere it is determined as m = sec θ where θ is the zenith angle corresponding to the given path. The Beer–Lambert law for the atmosphere is usually writt…
