In 1976, on the occasion of the Centennial of the Ameri can Chemical Society, H. A. RESrnG and C. G. WADE organized an international symposium on magnetic resonance in collo1d and in terface science which brought together a large number of scien

High resolution nuclear magnetic resonance measurements were made on the 19 F line of antimony pentafluoride intercalated in graphite. Two types of graphite were used in the synthesis of the compound — natural and synthetic. Two lines, one broad an

For imperfectly ordered two-dimensional systems in which motional averaging over the distribution of orientations does not occur, the chemical shift anisotropy pattern can reflect the details of the orientational distribution function: calculated spe

The usefulness of C-13 NMR spectroscopy and chemical shift for the study of charge transfer in graphite intercalation compounds is demonstrated. A linear relationship is established between the chemical shifts and the square root of the absolute valu

Carbon-13 NMR spectroscopy, employing high power decoupling and magic angle spinning, has been used to determine the availability of amine functionality of 4-vinylpyridine on charcoal for quaternization with 13C enriched methyl iodide. The quaternary

For the first-stage ternary ammonia-alkali metal-graphite intercalation compounds M(NH3)(x)C24(x of about 4, M = K, Rb, Cs), three sets of triplet H-1 NMR spectral lines have been observed at various temperatures and orientations due to the H-1 - H-1

NMR relaxation times, linewidths, and intensities for 27Al in NaX zeolite materials are compared for a hydrolyzed specimen and a specimen carefully protected against hydrolysis. The only parameter differing between the two materials is the relative i

The C-13 NMR chemical shifts of graphite intercalation compounds have been calculated. For acceptor types, the shifts come mainly from the paramagnetic (Ramsey) intra-atomic terms. They are related to the gross features of the two-dimensional band st
