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 ...

The researchers tested their method, which they term field-resolved infrared spectroscopy (FRS), on several biological samples. In measurements of human blood serum, they detected changes as small as ...

For IR spectroscopy, a nonlinear optical crystal converts some of the NIR pulses to MIR ones. After passing through a sample, the two types of light pulses are steered to different detectors.

A joint international research team has, for the first time, unveiled the crucial link between the structure of the solid ...

Infrared spectroscopy is also a significant addition to the environmental analysts’ armamentarium, especially with the introduction of long-range infrared sensors that can determine the ...

Near-infrared Spectroscopy. Near-infrared spectroscopy (NIRS) has been widely utilized in food and feed, polymers and textiles since the 1980s, with other industries such as pharmaceuticals, personal ...

Techniques such as Raman spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR), and near-infrared (NIR) spectroscopy provide detailed biochemical fingerprints ...

Infrared (IR) spectroscopy has long been recognized as a powerful biophysical tool for determining protein secondary structure and monitoring dynamic structural changes.
