متن کاملMAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON
The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...

and 0.33) fluorescent quantum yields of the longest chain pair, 3 and 6. The somewhat longer intrinsic lifetimes of the sulfur compounds ,are almost compensated by their lower fluorescent quantum yields SQ that the oxygen and sulfur compounds of comparable chain length have nearly the same predicted lifetimes. Since t:hese predicted observable lifetimes were determinedl in dilute solutions with...
متن کاملTheory of Saturation and Double Resonance Effects in Electron Spin Resonance
The theory of saturation and line widths in the electron spin resonance spectra of dilute solutions of free radicals has been extended to include incipient effects of chemical exchange and spin-spin or Heisenberg exchange processes as well as the effects of intramolecular terms such as the g-tensor, spin-rotational, and electron-nuclear dipolar (END) interactions. The development is based on an...
