Refractive spectroscopy

WebInfrared (IR) radiation is characterized by wavelengths ranging from 0.750 -1000μm (750 - 1000000nm). Due to limitations on detector range, IR radiation is often divided into three smaller regions: 0.750 - 3μm, 3 - 30μm, and 30 - 1000μm – defined as near-infrared (NIR), mid-wave infrared (MWIR), and far-infrared (FIR), respectively (Figure 1). WebATR is a contact sampling method that involves a crystal with a high refractive index and excellent IR transmitting properties. ATR is one of the more popular sampling techniques used by FT-IR Spectroscopists because it is quick, non …

WebAttenuated total reflectance infrared spectroscopy (ATR-FTIR) involves passing an incident ray of infrared light through a hemispherical crystal of a high refractive index material such as Ge, which reflects off the internal surfaces in contact with the functionalized sample. From: Encyclopedia of Interfacial Chemistry, 2024 View all Topics 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. home theatre power center
