Photochemistry of Furyl- and Thienyldiazomethanes: Spectroscopic Characterization of Triplet 3-Thienylcarbene [PDF]

, 2012
Photolysis (λ \u3e 543 nm) of 3-thienyldiazomethane (1), matrix isolated in Ar or N2 at 10 K, yields triplet 3-thienylcarbene (13) and α-thial-methylenecyclopropene (9). Carbene 13 was characterized by IR, UV/vis, and EPR spectroscopy. The conformational

Perspective on methane capture strategies from natural low-level emissions

Energy Nexus
Climate change is a pressing issue that confronts human existence in today’s world, and its consequences have already started manifesting at a more rapid rate. The biggest culprit of climate change is methane (CH4), a potent greenhouse gas. Consequently,

Electron paramagnetic resonance spectroscopy in radiation research: Current status and perspectives

Journal of Pharmacy and Bioallied Sciences, 2010
Exposure to radiation leads to a number of health-related malfunctions. Ionizing radiation is more harmful than non-ionizing radiation, as it causes both direct and indirect effects.

In One Fell Sweep: Modeling Exchange, Hyperfine and Dipolar Interactions from EPR Spectra of Copper(II) Spin Triangles

Magnetochemistry, 2023
The weak intramolecular magnetic interactions within a series of CuII3 complexes based on the trinucleating 2,4,6-tris(di-2-pyridylamino)-1,3,5-triazine (dipyatriz) ligand were investigated via Electron Paramagnetic Resonance (EPR) spectroscopy. X- and Q-

EPR and pulsed ENDOR study of intermediates from reactions of aromatic azides with group 13 metal trichlorides [PDF]

, 2013
The reactions of group 13 metal trichlorides with aromatic azides were examined by CW EPR and pulsed ENDOR spectroscopies. Complex EPR spectra were obtained from reactions of aluminium, gallium and indium trichlorides with phenyl azides containing a ...

Identification of fish irradiation by EPR spectrometry: Signal intensity and stability [PDF]

E3S Web of Conferences
In this work, the application of electron paramagnetic resonance spectroscopy for assessing the irradiation of fish is described. Pink salmon was chosen as the research object and irradiated at 3 and 6 kGy doses. A linear correlation was observed between

EPR Spectroscopy: A Powerful Tool to Analyze Supramolecular Host•Guest Complexes of Stable Radicals with Cucurbiturils

Molecules, 2020
Stable organic free radicals are increasingly studied compounds due to the multiple and unusual properties imparted by the single electron(s). However, being paramagnetic, classical methods such as NMR spectroscopy can hardly be used due to relaxation ...

Rapid Scan Electron Paramagnetic Resonance Spectroscopy Is a Suitable Tool to Study Intermolecular Interactions of Intrinsically Disordered Protein

Biology, 2023
Intrinsically disordered proteins (IDPs) are involved in most crucial cellular processes. However, they lack a well-defined fold hampering the investigation of their structural ensemble and interactions.
