MAGNETISATION 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 ...
متن کاملAn Electron Spin Resonance Study of Neoplasms.
Twenty-nine types of mouse tumor and two normal mouse tissues were examined in the frozen state by electron spin resonance spectroscopy, and the redox states of some components were characterized. Intracellular organelles of mouse hepatoma and of normal mouse liver were separated by differential centrifugation and examined by elec tron spin resonance spectroscopy. The major difference between t...
متن کامل2-Amino-4-methyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile
In the title compound, C(10)H(12)N(2)S, the thio-phene ring is essentially planar (r.m.s. deviation = 0.0290 Å). The two C atoms of the cyclo-hexene ring (at positions 6 and 7) are disordered over two sets of sites in a 0.810 (5):0.190 (5) ratio. The cyclo-hexene rings in both the major and minor occupancy conformers adopt a half-chair conformation. In the crystal, there are two types of N-H⋯N ...
متن کاملAn Electron Spin Resonance Study of Some Hemoproteins.
The magnetic characteristics of hemoproteins are a manifestat,ion of electron distribution. They are sensitive to the nature of t.he ligands occupying the fifth and sixth coordination positions of the iron atom, which also determine the function of the hemoprotein. Theorell and his school (1) have systematically studied the magnetic properties of various hemoproteins and their derivatives by ma...
متن کاملElectron Spin Resonance of Free Radicals and Radical Pairs in Irradiated Single Crystal of 1-Methyluracil
ion radical 1 After irradiation of single crystals at room tem perature abstraction and addition radicals of types 1 and 2 give rise to a complex composite ESR spec trum. Annealing for about 20 min at 200 °C or storage for about two months at room temperature greatly simplifies the spectral pattern indicating the survival of the abstraction radical only. The same spectrum is also seen after i...
