TL;DR: In this paper, the first observation of IR-active optic modes in donor graphite intercalation compounds was reported, and the lattice mode effective charge indicates a significant amount of dynamic charge residing in the interior graphitic layers.

TL;DR: In this article, a theoretical model for the phonon dispersion relations of acceptor and donor graphitic optic modes is presented. But the experimental results show that the graphitic mode stiffens as a function of reciprocal stage for acceptor compounds and softens for donor compounds.

TL;DR: In this paper, two new applications of (00 l ) X-ray scattering intensity data for graphite intercalation compounds were reported, yielding the structure of sandwich intercalates, as in metal chloride compounds, and an estimate of the state index via the l -value at maximum scattering intensity.

TL;DR: In this paper, the preparation and stage characterization of high stage (n⪖5) potassium and rubidium donor compounds are discussed, with particular emphasis given to low order index reflections.
