Hi
In UV spectrscopy, is the definition of absorbance (A = ecl) derived from the definition of transmission (T = It/Io) where It is the transmitted light and Io is the incident light, or is the definition of transmission defined from absorbance.
Also A = -log(T) and T = 10^-A = 10-ecl.
It looks to me as though transmission is a physical quantity based on recorded data and then the definition of absorbance is based on this
thanks
