Computational Investigation of Spin Traps Using Hybrid Solvation Models.
… its phosphorylated analogues have been used as spin traps for the investigation of free radicals in biological systems. Theoretical work on these molecules suggests that there are important differences in their properties between biological systems and isolated molecules in the gas phase, most …

A study of mechanochemical reactions of spin traps in hydrocarbon polymers
The identification and quantification of spin adducts and their reduction products (>NOH, >NOR) formed from nitroso compounds and nitrones in EPR and PP during spin trapping techniques have been examined. The nitroxyl yield and polymer bound nitroxyl percentage formed from these spin traps were …

Chemical probes for the study of mitochondrial oxidative stress
… precursor ii. Three new pyridinium salt nitrone spin traps iv-vi, designed to accumulate in mitochondria, were synthesised using the Zincke reaction as the key pyridinium salt forming reaction. The compatibility of nitrones with the Zincke reaction was demonstrated for the first time. The …

Novel Methods to Characterise Atmospherically Relevant Organic Radicals and Reactive Oxygen Species
… both the gas and particle phase are presented. Spin trap molecules are used to scavenge CIs to form stable 1:1 adducts which are subsequently detected and quantified using mass spectrometry. The chemistry of CIs with spin traps is extensively investigated. The unique capability of this technique …
