Refractive spectroscopy

WebAug 18, 2024 · Abstract. We suggest a new modality of infrared spectroscopy termed Infrared Refraction Spectroscopy, which is complimentary to absorption spectroscopy. The beauty of this new modality lies not only in its simplicity but also in the fact that it closes an important gap: It allows to quantitatively interpret reflectance spectra by simplest means. WebFTIR spectroscopy is a powerful tool to qualify and quantify organic substances in the solid, liquid, or gaseous state. However, many sampling techniques require pre-treatment of samples in order to obtain high-quality spectra. ... Because of the differences in refractive indices of both materials, total internal reflection occurs. This ...
