摘要
SOLID-STATE <sup>13</sup>C nuclear magnetic resonance （NMR） technique is an effective method to study the texture of material. Under the condition of high magnetic field （400 MHz） and by the application of cross polarization, magic angle spinning （CP/MAS）, total sideband suppression （TOSS）, etc., the content of different textural carbons in kerogen has been quantitatively analyzed by the solid-state <sup>13</sup>C NMR spectroscopy of a series of kerogen of thermal simulation samples with R<sub>o</sub> value ranging from 0.64% to 1.76%. The results show that
