IUPAC - internal transmittance (08262)

internal transmittance symbols: $T_{i}$ , $τ_{i}$

Synonym: internal transmission

https://doi.org/10.1351/goldbook.08262

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.
