Definition of absorbance in English:


Line breaks: ab¦sorb|ance
Pronunciation: /əbˈzɔːb(ə)ns
, -ˈsɔːb(ə)ns/


A measure of the capacity of a substance to absorb light of a specified wavelength. It is equal to the logarithm of the reciprocal of the transmittance: a plot of absorbance versus wavelength would give a Gaussian curve [count noun]: absorbances were recorded with a clinical photometer
