A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has proposed a novel model optimization algorithm—External Calibration-Assisted Screening (ECA)— that ...

The vibrational excitation energy of molecules is in the range of 10 13 –10 14 Hz, which corresponds to infrared radiation. 5 This means that IR spectroscopy can be used to observe the vibrational ...

Nature - A fresh approach for infrared spectroscopy. The reliance of infrared spectroscopy on light transmission limits the sensitivity of many analytical applications.

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 ...

Optical PhotoThermal InfraRed (O-PTIR) is a new and alternative infrared spectroscopy method. Infrared spectroscopy has been around for 100 years and has been done dispersively and with ...

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 ...

Infrared spectroscopy products such as Fourier transform infrared (FTIR) spectrometers are used in petrochemical engineering, food analysis, organic synthesis, in the pharmaceutical industry, in ...

But adapting infrared spectroscopy to work in a more mobile format could open up some interesting possibilities, such as detecting gas leaks in a mine shaft, or preventing food spoilage.

A team at Kyoto University has now demonstrated another possible answer employing quantum infrared spectroscopy, using visible and infrared photon pairs in a quantum entangled state. Published in ...

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, ...
