Max absorbance symbol
Did you know?
WebTo quantify the amount of light that is absorbed, we define the absorbance as I 1 I 0 = 10−A → A = −log10( I 1 I 0) I 1 I 0 = 10 − A → A = − log 10 ( I 1 I 0) Note that the absorbance is unitless. In this case, we can plot an absorption spectrum – a graph of the absorbance $A$ as a function of the wavelength of a sample:
