... reactions cause a continuous increase in the proportion of sp2 (i.e., C=C) bonds with decrease of sp3 (i.e., C-C) bonds. For instance, Figure 1 shows a set of Raman spectra for coal samples varying in their maturity. Increased sp2 leads to blue shift of the G peak, whereas decreased sp3 leads to red shift...

...-) and D- (Disordered) bands in each Raman spectrum were fit algorithmically to a multi-peak model, yielding a number of diagnostic parameters that correlate with changes occurring in samples as a result of thermal maturation and pyrolysis. Parameters extracted from analysis of Raman spectra were plotted...

... Abstract Objectives/ Scope: There is a strong correlation between the ordered and disordered C-C peaks observed in Raman spectra and conventional vitrinite reflectance values that encourage the use of Raman microscopes to characterize micron-sized particles that are not detected with optical...
