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 ...

Infrared spectroscopy is increasingly established as a way to carry out in vitro diagnostic testing, thanks to its ability to detect the molecular profiles of many biomarkers. What has been missing, ...

What is Surface-Enhanced Infrared Absorption (SEIRA) Spectroscopy? Surface-enhanced infrared absorption (SEIRA) spectroscopy is an advanced analytical technique that combines the principles of ...

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, ...

Infrared vibrational spectroscopy could enable the production of high-resolution maps of molecules inside live cells and cell organelles. A new study from Helmholtz-Zentrum Berlin (HZB) and Humboldt ...

The sample preparation before conducting an infrared spectroscopy (IR) study is as critical as the study itself, and the samples which are difficult to dissolve in any IR-transparent solvent are mixed ...

This paper explores the differences and similarities between Raman and infrared spectroscopy in regard to unknown material identification and reaction monitoring. While these techniques share ...
