Electron Paramagnetic Resonance
then the electron will transition from the lower energy state to the higher energy state. The frequency at which absorption occurs is known as the resonant frequency due to similarities the system
Free-radical scavenging capacity and antioxidant activity of selected plant species from the Canadian prairies
Ethanolic extracts from the roots of wild licorice (Glycyrrhiza lepidota), narrow-leaved echinacea (Echinacea angustifolia), senega (Polygala senega), leaves of bearberry (Arctostaphylos uva-ursi)
Electron paramagnetic resonance : elementary theory and practical applications
PREFACE. ACKNOWLEDGMENTS. 1 BASIC PRINCIPLES OF PARAMAGNETIC RESONANCE. 1.1 Introduction. 1.2 Historical Perspective. 1.3 A Simple EPR Spectrometer. 1.4 Scope of the EPR Technique. 1.5 Energy Flow in
A review of electron spin spectroscopy and its application to the study of paramagnetic defects in crystalline quartz
A comprehensive review (ca. 230 references) is presented of the present (1983) state of knowledge of paramagnetic defects in crystalline quartz, as derived from electron paramagnetic resonance
EPR of iron centres in silicon dioxide
A review is presented of the present status of EPR-based understanding of Fe in SiO2. As a primary goal, a guide to the literature is given. Quantitative evaluation of all relevant spin-Hamiltonian
The magnetic properties of the oxygen-hole aluminum centers in crystalline SiO,. 11. (A104/H+)+ and (A104/Li+)+
The centers [AIO,/M+]+, formed in a-quartz by X-irradiation at 77 K. contain an aluminum ion substituted for a silicon ion, with an electron removed from a neighboring oxygen by the ionizing
Simulation of magnetic resonance powder spectra
Abstract The rapid simulation of magnetic resonance powder patterns by computer is discussed. Several methods of modeling sets of crystallite orientations are briefly considered and compared to the
A Review of the EPR Spectroscopy of the Point Defects in α-Quartz: The Decade 1982–1992
A review (126 references) is presented of progress made, primarily in the decade 1982–1992, in the field of electron paramagnetic resonance spectroscopy of ‘point’ defects occurring in crystalline
