Beer-Lambert Law in Spectroscopy #organicchemistry

The Beer-Lambert Law states that the amount of energy absorbed by a solution is proportional to the path length and concentration. Put simply, a more concentrated solution absorbs more light than a dilute solution does.

The Beer-Lambert Law equation is as follows: A = ϵ.d.c

Where ϵ = molar absorptivity, d = path length and c = concentration.
Molar absorptivity is a unique physical constant of the sample that relates to the sample’s ability to absorb light at a given wavelength. ϵ has the unit as L·mol-1·cm-1.
