IR Semitransparent materials measurements Andrew Szelc 6/20/2006

I am looking for some info regarding measurements of IR semitransparent materials.

Knowing the material's density and absorption coefficent for a given wavelength, is it possible to assess the material''s temperature "inside" of the observed specimen?

Are there any theoretical/mathematical models describing how the heat confined "inside" of the material contributes to the total emited energy?

I will appreciate any info.

Thank you in advance.

Writing the equation giving the flux exiting from a semitransparent material is not that difficult, assuming that the material is either isothermal, or you know the temperature profile.
