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 ...

Researchers from Tokyo Metropolitan University have measured how oxygenated hemoglobin levels in the blood change in infants' brains in response to touch. Using spectroscopy methods with external ...

To investigate how melanin affects the accuracy of near-infrared spectroscopy (NIRS) measurements, researchers correlated the melanin levels of 35 adults with a diverse range of skin tones, measured ...

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 has emerged as a versatile tool for probing protein structures and dynamics by detecting the vibrational modes of chemical bonds. Its non-invasive nature and high sensitivity ...

Inks and paints are everywhere in the world around us. As well as for writing and printing, these materials are also used for protection against the elements and aesthetic reasons. These substances ...

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 ...

Virtually every scientific field has made strides by harnessing light to study the properties of substances. This technique, called spectroscopy, has countless research applications, and innovations ...

The team found the same peaked response in oxygenated hemoglobin levels in infants of different ages over their first year. Tokyo, Japan – Researchers from Tokyo Metropolitan University have measured ...
