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 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 ...

Photothermal AFM-IR is a highly effective method for nanoscale chemical analysis, ideally suited to the stringent requirements of semiconductor research and production. By integrating the spatial ...

Spectroscopy is the study of how electromagnetic radiation interacts with matter and is used as an analytical technique in many scientific disciplines. 1 The key properties of light, including ...
