S-band electron spin echo and multifrequency EPR investigations of disordered solids
Electron spin echo (ESE) methods are particularly useful for measuring weak electron-nuclear couplings in paramagnetic solids. Frequencies that correspond to nuclear transitions are manifested in the electron spin echo envelope modulation (ESEEM) patterns recorded from a sample. Information …

Coherent control of hyperfine-coupled electron and nuclear spins for quantum information processing
Coupled electron-nuclear spins are promising physical systems for quantum information processing: By combining the long coherence times of the nuclear spins with the ability to initialize, control, and measure the electron spin state, the favorable properties of each spin species are utilized. This …

Magnetic Resonance Studies of Inorganic Oxides and a New Pulse Programming System for Pulsed EMR
… inorganic oxide systems using nuclear and electron magnetic resonance spectroscopies and also report a new pulse programming system for a pulsed S-band EMR spectrometer. We show in a study of simple perovskites (Ca,Sr,Ba)(Ti,Zr) O$\sb3$ that magic-angle spinning O-17 NMR provides unique, …

A single-crystal EPR study of radiation-induced defects in selected silicates
This thesis presents a series of single-crystal electron paramagnetic resonance (EPR) studies on radiation-induced defects in selected silicate minerals, including apophyllites, prehnite, and hemimorphite, not only providing new insights to mechanisms of radiation-induced damage in minerals but …

The Binding Pockets of QA and QB in the Photosynthetic Reaction Center of Rba. sphaeroides Probed by Pulsed EPR
… absorption by the reaction center results in electron transfer through a series of cofactors, the final two are identical ubiquinones (QA and QB). Both ubiquinones can be stabilized in their reduced (semiquinone) state allowing for their binding pockets to be studied with EPR (electron …
