Ultraviolet-visible (UV-Vis) spectroscopy is a widely used technique in many areas of science ranging from bacterial culturing, drug identification and nucleic acid purity checks and quantitation, to quality control in the beverage industry and chemical research. This article ...
[Nat. Chem. 6, 697 (2014)], we studied the excess (hydrated) electron in water with the help of transient THz spectroscopy, which is a sensitive probe of its delocalization length. In that work, we used laser pulses at 800 nm, 400 nm, and 267 nm for photoionization. While the ...
Hydroxyl radicalUltraviolet absorptionUV transition probabilitiesThe publication by G.H. Dieke and H.M. Crosswhite ( JQSRT 1962;2:97–199) is a classic paper detailing the spectroscopy of the A 2Σ +← X 2Π bands of the hydroxyl radical (OH) in the ultraviolet region. It soon became ...
However, only trace amounts of amorphous material were produced, unsuited for X-ray diffraction (XRD) experiments.1H nuclear magnetic resonance (NMR) spectroscopy of the isolated material showed protons in the 6–8 ppm range (implying aromatic functionality), but again with insufficient sensitivity f...
To assess whether the DP polymer and the scaffolds undergo some changes associated with the electrospinning process or upon storage and UV sterilization, the different scaffolds were analyzed with Fourier Transformed Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC). Incorporation of...

Abundances of a range of air pollutants can be inferred from satellite UV-Vis spectroscopy measurements by using the unique absorption signatures of gas species. Here, we implemented several spectral fitting methods to retrieve tropospheric NO2, SO2, and
(NMR) spectroscopy, Mass Spectrometry (MS), which includes gas chromatography and Matrix-Assisted Laser Desorption/Ionization, (MALDI)-MS79. However, the majority of work has been done on LPS from Gram-negative bacteria, while information on cyanobacterial LPSs has been limited and sometimes ...
