Transmittance fully corrected for surface effects and effects of the cell, such as reflection, scattering, luminescence, and vignetting losses.
Note:
If scattering and luminescence in the sample are negligible, \(\alpha_{\rm{i}} + Τ_{\rm{i}} = 1\), where \(\alpha_{\rm{i}}\) is internal absorptance.
