- Analysis
- Iterative inversion of n and k with full optical model of the film+substrate + Kramers-Kronig analysis over 950-4000cm-1 range and n($15800cm^{-1}$)= 1.58 (F. Trotta thesis 1996) - k is set to 0 and n is interpolated outside H2S bands to remove noise and OCS ($2039cm^{-1}$) and CO ($2136cm^{-1}$) bands
