τ_{i}

synonym: internal transmission

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,

α_{i} + Τ_{i} = 1

, where

α_{i}

is internal absorptance.
