A spectrometer that directly detects the vibrational “fingerprint” of molecules offers a sensitive new way of deducing a material’s chemical make-up. The device, which was developed by researchers in ...

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 ...

Far-field mid-infrared (MIR) spectroscopy has an increasingly important role for numerous applications (for example, chemical detection 1, food safety 2 and bio-sensing 3) through directly probing ...

The cell is grown on a Si-C-Membrane and embedded in its liquid medium. The tip of the s-SNOM detects vibrations, probed by Infrared-Light from BESSY II. Infrared vibrational spectroscopy at BESSY II ...

According to a study published in Nature Communications, researchers have created an extremely sensitive detector for identifying molecules based on their infrared vibrational “fingerprint.” ...

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 ...

Infrared and Raman spectroscopies can observe different types of molecular vibrations. Using both methods on a compound provides a more complete molecular picture than either alone. But the two ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

NIR spectroscopy concerns the analysis of how NIR light and matter interact. In spectroscopic analysis, light is determined by the wavelength, not by the applied energy. The wavelength of light is ...

A new method for broadband THz–fingerprint Raman spectroscopy at an ultrafast spectral rate enables synchronous measurement of two distinct types of vibrational signals, for dual-region sensitivity ...

Photothermal AFM-IR, or AFM-IR, is an analytical method used for chemical identification in a materials sample at the nanoscale. AFM-IR incorporates both the nanoscale spatial resolution of atomic ...
