IR spectroscopy, or infrared spectroscopy, is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. It measures the absorption of ...

Enhanced light-matter interactions are the basis of surface-enhanced infrared absorption (SEIRA) spectroscopy, and conventionally rely on plasmonic materials and their capability to focus light to ...

When things vibrate, they make sounds. Molecules do too, but at frequencies far beyond human hearing. Chemical bonds stretch, bend, and twist at characteristic rates that fall in the infrared region ...

A spectrometer that directly detects the vibrational “fingerprint” of molecules offers a sensitive new way of deducing a material’s chemical make-up. The device, which was developed by researchers in ...

Infrared spectroscopy is a non-invasive tool to identify unknown samples and known chemical substances. It is based on how different molecules interact with infrared light. You may have seen this tool ...

Infrared and Raman spectroscopies can observe different types of molecular vibrations. Using both methods on a compound provides a more complete molecular picture than either alone. But the two ...

Researchers developed IRiSTM, a technique that combines infrared light and scanning tunneling microscopy to detect vibrations from a single molecule.

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

Molecular vibrations, when paired with near-infrared (NIR) light, have opened a new chapter in cancer treatment. Instead of relying on radiation or chemicals, scientists now use finely tuned molecules ...
