Infrared (IR) spectroscopy, alternatively referred to as vibrational spectroscopy, is an analytical technique used in chemical and physical sciences. This spectroscopic technique measures how samples ...

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 ...

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 ...

Australian researchers used mid-infrared spectroscopy and explainable machine learning to accurately predict how much stable ...

In the agricultural and food industry, determining the chemical composition of raw materials is important for production efficiency, application, and price. Traditional laboratory testing is ...

Spectroscopic analysis can identify microplastics, including how FT-IR and Raman microscopy support accurate particle ...

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 ...

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 ...

Raman spectroscopy, unlike infrared, reaches sub-micrometer resolution but is hindered by weak signals and fluorescence ...

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 ...
