TL;DR: In this paper, the ESR spectrum was presented for the perfluorocyclobutane radical anion prepared by gamma radiation at 77/sup 0/K of a solid solution of 5 mole percent of perfluoric acid in neopentane.
Abstract: The ESR spectrum was presented for the perfluorocyclobutane radical anion prepared by ..gamma.. radiation at 77/sup 0/K of a solid solution of 5 mole percent of perfluorocyclobutane in neopentane. Studies were performed using photobleaching experiments by exposing the sample to unfiltered light from a tungsten lamp. (DDA)

TL;DR: In this paper, the e.s.r. spectrum of the CH2HgCl radical in γ-irradiated polycrystalline methyl mercuric chloride has been analyzed for quadrupole effects; a detailed interpretation yields the following set of parameters: g⊥= 1.990; 1A ⊥(2H)= 19.5 G; 199A⊦(Hg)= −437 G; 201A⌉(HG)=+162 G; e2Qqz(201Hg))=
Abstract: The e.s.r. spectrum of the CH2HgCl radical in γ-irradiated polycrystalline methyl mercuric chloride has been analyzed for quadrupole effects; a detailed interpretation yields the following set of parameters: g⊥= 1.990; 1A⊥(2H)= 19.5 G; 199A⊥(Hg)=–437 G; 201A⊥(Hg)=+162 G; e2Qqz(201Hg)=–900 ± 50 MHz. The value obtained for the 201Hg nuclear quadrupole coupling constant is comparable to the results obtained in previous studies on mercuric chloride (from pure quadrupole resonance spectra of the solid) and methyl mercuric chloride (from microwave spectra of the gas).
