Experimental measurements of the hyperfine coupling constants of anthracene and azulene
anions with various solvents and cations are presented. It is shown that the proton coupling …

The electron paramagnetic resonance of Mn 2+ ions in powders and single crystals of PbTe
and gadolinium-doped PbTe is reported. Resolved hyperfine and superhyperfine lines were …

X-band EPR measurements have been made on single crystals of lead telluride doped with
gadolinium in nominal concentrations of 0.04, 0.1, 0.5, and 1.0 atomic %. Fully resolved fine …

The chlorine resonance in titanium tetrachloride has been re‐examined, confirming the
existence of four resonances. A chlorine‐35 resonance at about 6 Mc has been discovered in …

The proton hyperfine coupling constants of the azulene anion in dimethoxyethane with lithium
ions show systematic variations of the order of 10% as temperature and concentration are …

Data are presented for the proton and cation hyperfine coupling constants and g values of
the naphthalene anion as a function of solvent, cation, and temperature. The variation of the …

The oxidation of anthracene by thallium (III) trifluoroacetate (TTFA) in trifluoroacetic acid (TFA)
has been reinvestigated. We have interpreted the observed EPR spectra in terms of the 9-…
