Several sets of field-ionization mass spectral data are being interpreted. The data are from oils, asphaltenes, and preasphaltenes-1 fractions. Several experiments with preasphaltenes-2 showed that three fractions could be obtained with silica gel chromatographic systems. However, some difficulties were encountered in handling the preasphaltenes-2 material with the chromatographic systems. Several lower molecular weight hydroxyl aromatic structures were characterized in amonohydroxyl aromatic fraction from the oils of F-45. A substantial amount of field-ionization mass spectrometry (FIMS) data and elemental analysis data was obtained from polycyclic aromatic hydrocarbons, nitrogen heterocycles, and hydroxyl aromatics from oils and asphaltenes. However, some of the fractions showed low volatility by FIMS and the carbon content of most of the fractions was low. The low volatility and carbon content are being investigated. The paper in Appendix A, ''Estimation of aromatic and hydroaromatic content in complex hydrocarbon samples by liquid chromatography and field-ionization mass spectrometry'' was processed separately for inclusion in the Energy Data Base. 7 figs., 3 tabs.
