High field 13C N.M.R. in lamellar compounds of graphite and a model of “in plane localized” densities of states

A detailed line shape analysis was obtained employing high field resonance and good signal to noise ratio. Stage II donor compounds clearly reveal two axially anisotropic lines and Knight shifts. These shifts have been analyzed as being the sum of isotropic and anisotropic contributions. The graphit...

Description
Summary:A detailed line shape analysis was obtained employing high field resonance and good signal to noise ratio. Stage II donor compounds clearly reveal two axially anisotropic lines and Knight shifts. These shifts have been analyzed as being the sum of isotropic and anisotropic contributions. The graphite line, with its anisotropy, is now better resolved, and is a more accurate reference. A better description of the line component parameters has now been obtained. With this analysis, all acceptor compounds show a common shift with a unique kind of carbon. The relation between measured shifts, local density of states, and transferred charge is discussed.
