Raman spectra of graphite fibers intercalated with K, Rb and Cs are reported. X-Ray diffraction is used to characterize the fibers with respect to staging. We report results mainly for GY70, a highly graphitic commercially available fiber, which is polyacrylonitrile (PAN) based, and some results on

โฆ Synopsis
We have assembled a Raman microprobe to perform Raman spectroscopy studies of intercalated graphite fibers. This instrument allows rapid acquisition of data at a spatial resolution of 2 pm. Staging homogeneity has been examined in FeCI1-and K-intercalated benzene-derived graphite fibers, and is found to be similar to that observed in HOPG-based compounds.

The nuclear hyperfine technique of time-differential perturbed angular correlations has been applied to the study of graphite intercalation compounds. Values are obtained for the electric field gradients and the quadrupole frequencies of the intercalated probe nuclei. Specifically, three species are
