摘要: Abstract In the reflection mode of spectroscopic measurements, IR radiation impinges on surface a sample and intensity specularly reflected light is recorded. This an easy to use, non-contact non-destructive sampling technique suitable for samples with flat smooth surfaces. The spectra obtained via external depend number factors differ considerably from standard transmission spectra. These differences are explained experimental that affect nature discussed.
