从干酪根的固体~(13)C核磁共振(NMR)交叉极化(CP)魔角旋转(MAS)得到的谱图中,可以直接得出干酪根中有机碳结构的各种信息,用以表征干酪根的类型、成熟度、生烃潜力与演化规律。在这类谱图中,带质子芳碳与桥接芳碳的化学位移互相重叠,限制了我们对芳簇结构的认识。偶极相移的基本原理在于带质子碳与不带质子碳的横向弛豫时间(T′_2)差 From the spectra of kerogen (13C) nuclear magnetic resonance (CP) magic angle rotations (MAS) from kerogen, various information on the organic carbon structure in the kerogen can be derived directly Characterization of kerogen types, maturity, hydrocarbon generation potential and evolution. In these spectra, the chemical shifts of the protonated aromatic carbons and the bridged aromatic carbons overlap each other, limiting our understanding of the aromatic cluster structure. The basic principle of dipole phase shift lies in the difference between the lateral relaxation time (T’_2) with proton carbon and proton-free carbon
