carbon samples, the spectra were deconvoluted into the D
band (1,343–1,352 cm–1), G band (1,572–1,581 cm–1),
and S band (2,699–2,719 cm–1). All four low carbon sam-
ples are characterized by a low intensity D band a high
intensity, narrow G band and a broad S band (Figure 7).
These characteristics suggest that all four low carbon sam-
ples contain crystalline CM. In the high carbon samples,
the averaged spectra were deconvoluted into the D band
(1,338–1,340 cm–1) and the G band (1,600–1,604 cm–1).
All four high carbon samples are characterized by a broad,
relatively high intensity D band a high intensity, relatively
narrow G band and no detectable S band (Figure 8). These
characteristics suggest that all four high carbon samples
contain amorphous CM.
Table 4 summarizes the results from the Raman charac-
terization of the eight selected head samples. Carbon with
