Next, provided aromaticity is also known (fa for W, 0.35; for GS, O.5l), the disk weight (weight of aromatic carbon atoms in a single sheet) and the layer diameter also dan'be approxi- mated. These values are also listed in Table 11. Experimental values for the W and GS asphaltenes from a previous paper (15) are included: It i is of interest that the unit weight values obtained from GPC, mass spectrometry, x-ray diffraction and the electron microscopic measurements agree in general magnitude with the weights obtained by the present method. Deviations of the disk weight of GS calculated from resistivity from that obtained by mass spectrometry may by due to the polydispersity of the GS asphaltene (e.g., Mw/MN for VY is 1.27; for GS, 1.74 (15)). From Table 11, the asphaltene-iodine complexes formed appear to correspond to an 12:asphaltene ratio of about l.5:l. This composition is J shown in model A of Fig. 8. Actually aromatic disks of the size present in asphaltenes should be able to accomodate more than one molecule of iodine. Finally the increase in the free spins, as demonstrated by the EPR spectra, may be indicative of an increase in carrier concentration (2). The nature of these charge carriers will have a strong bearing on the conduction mechanism and will be the subject of a separate investigation. . < ACKNOWLEDGMENT The authors thank Mr. Timothy R.
