Attenuated Total Reflectance (ATR) is a powerful measurement technique used in FT-IR spectroscopy. Let’s explore its applications and how it works: 1. Identification of Chemical Compounds: ATR-FTIR spectroscopy helps identify chemical compounds by analyzing their unique infrared absorption patterns. It’s particularly useful for characterizing organic and inorganic materials. 2. Studying Molecular Structures: ATR provides insights into molecular structures, including functional groups and bonding arrangements. Researchers use it to investigate polymers, proteins, and other complex molecules. 3. Surface Properties Examination: ATR allows surface analysis without extensive sample preparation. It’s valuable for studying thin films, coatings, and interfaces. 4. Analyzing Polymers: Polymer characterization benefits from ATR due to its ability to analyze solid samples directly. Researchers study polymer composition, additives, and degradation. 5. Biomolecule...
