Perinaphthenyl
WebOur calculated results show that the perinaphthenyl radical (R1) has a spin of 1/2. However, in its [R1]2 dimer structure, the net spin becomes zero due to an antiferromagnetic spin-exchange between radicals. To avoid antiferromagnetic spin-exchange of identical face-To-face radicals, ... WebThis sheet is about exposure to phenylephrine in pregnancy and while breastfeeding.

WebThe electron spin resonance spectrum of the perinaphthenyl radical has been studied in the isotropic and nematic phases of p-azoxyanisole. The g tensor and hyperfine splitting tensors for the two proton couplings and three of the four carbon-13 couplings have been determined, and were found to agree in most cases with theoretical estimates. WebJan 3, 2001 · The electron affinities of benzene and four polycyclic aromatic hydrocarbons (PAHs), naphthalene, anthracene, tetracene, and the perinaphthenyl radical, have been obtained using six common density functional theory (DFT) methods.
