experimental absorbance

symbol: $A_{10}$
https://doi.org/10.1351/goldbook.08247
Decadic absorbance as measured with no corrections for other processes.
Notes:
  1. The term emphasizes that radiation might be lost from the beam by reflection, luminescence, scattering, and possibly vignetting (e.g., spectral shifts introduced from changing a radiation beam diameter or shape), and not solely by absorption.
  2. Internal absorbance is used to term absorbance corrected for other processes.
