What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

The nature and extent of hydrogen bonding in water has been scrutinized for decades, including how it manifests in optical properties. Here we report vacuum ultraviolet absorption spectra for the ...

An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear frequency ...

Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

Ultraviolet light has always sat at the edge of human perception, powerful yet invisible, more associated with sterilizing ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

(Nanowerk News) In a recent publication in Nature ("Near-ultraviolet photon-counting dual-comb spectroscopy"), researchers at the Max Born Institute (MBI) in Berlin, Germany, and at Max-Planck ...

Chemistry, a branch of science so universally applicable, includes fields of study spread across the map. These divergent studies in the field of chemistry indicated that chemists and researchers ...
