Infrared spectroscopy (IR spectroscopy) is an optical technique that detects molecular bond vibrations and rotations upon absorption of infrared light. Because different chemical functional groups ...

Catalysis lies at the heart of modern chemistry, underpinning sustainable energy conversion, chemical manufacturing, and environmental remediation. Yet, many of the most critical questions in ...

FTIR deals with the infrared region of the electromagnetic spectrum, and it works by measuring how much light is absorbed by the bonds of vibrating molecules to provide a molecular fingerprint. The ...

NIR spectroscopy concerns the analysis of how NIR light and matter interact. In spectroscopic analysis, light is determined by the wavelength, not by the applied energy. The wavelength of light is ...
