Schematic representation of Raman spectroscopy. After the sample (molecule) is exposed to an intense beam of monochromatic light in the frequency range of visible, near-infrared or near-ultraviolet ...
Functional near-infrared spectroscopy, or fNIRS, measures changes in metabolic activity. It does this by passing infrared light through the skull to monitor blood flow. Both methods can monitor ...
Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...
SEIRA spectroscopy amplifies molecular vibrational signals by utilizing the infrared near-field enhancement provided by rough metal surfaces or metallic nanostructures. Its primary advantage is ...
