We have used EPR spectroscopy to determine the rate of spin exchange between cation radicals held in rigid polymeric matrixes. Radicals of this type are thought to be the charge carriers during ele...

Analysis of electron-nuclear double resonance (ENDOR) spectra from randomly oriented solid samples requires knowledge of all polar angles which contribute to fixed resonance fields in the electron paramagnetic resonance (EPR) spectrum of the sample.

Electron paramagnetic resonance spectra and nitrogen ENDOR powder spectra have been obtained from copper complexes of tetraphenylporphyrin, meso-tetrakis(2-methylpyridinium-N-yl)porphyrin (ortho), meso-tetrakis(4-methylpyridinium-N-yl)porphyrin (para

The ENDOR resonances from ligand nuclei in paramagnetic transition-metal complexes exhibit a shift from the nuclear Larmor frequency because of the dipolar and Fermi contact interactions with the unpaired electron. The dipolar interaction has orienta

The ESR linewidths of solid samples of the di- t -butylnitroxide radical have been measured over an extended temperature range at three different Zeeman frequencies. The magnitude of both the exchange and dipolar interactions can be determined throug

Investigations of the E.S.R. linewidths of exchange narrowed lines from solid organic free radicals allow one to obtain information about both the exchange interaction and the electron-electron dipolar interaction in some instances. In cases in which

Measurements of the nuclear spin lattice relaxation times of the protons in solid samples of the di-t-butylnitroxide radical have been made. The relaxation times have been measured at different Zeeman frequencies as a function of concentration and of
