Evaluation of the fundamental absorption spectrum of a material by its refractive index dispersion in the transparency range
A method has been elaborated to reconstruct the material absorption spectrum k(ω') in the ranges of fundamental excitations (ω') basing on the refractive index dispersion n(ω) in the material transparency range (ω). The method has been applied to evaluate of the linear dichroism Δk(ω'...

A method has been elaborated to reconstruct the material absorption spectrum k(ω') in the ranges of fundamental excitations (ω') basing on the refractive index dispersion n(ω) in the material transparency range (ω). The method has been applied to evaluate of the linear dichroism Δk(ω') spectra of K₂Ca(SO₄)₂-H₂O crystals (syngenite) proceeding from its birefringence dispersion Δn(ω). The Δk(ω') spectra of syngenite have been obtained and analyzed for several temperatures in the range of 293 to 450 K for mechanically free and uniaxially pressed (σ = 250 bar) samples. |
