The electron paramagnetic resonance studies of methylene arc reviewed. The structural information that resulted include verification of the triplet multiplicity of the electronic ground state, the discovery of a bent geometry for the molecule with a bond angle of 134°, measurement of the zero-field or fine-structure splitting parameters, measurement of the g-factor tensor, and measurement of the isotropic and anisotropic 13C hyperfine interaction. The results are compared with recent measurements obtained with laser magnetic resonance techniques and theoretical treatments.

A high-frequency electron paramagnetic resonance (EPR) spectrometer with frequency modulation was developed. The advantages of the method for recording the EPR spectra of paramagnetic centers with giant fine-structure splitting in the case of non-Kramers ions in a garnet crystal were demonstrated.

AbstractThree different Electron Paramagnetic Resonance (EPR) signals, one trigonal and two orthorhombic, which originates from iron-indium pairs in silicon are investigated. It is shown that the two orthorhombic spectra can be explained as transitions within the two doublets of a S=3/2 system with a large zero-field splitting. The temperature dependence of-the intensities reveals that the newly discovered spectrum corresponds to the lower doublet and that the zero-field splitting is 9.8 ± 2.0 cm-1.
