In this study, products of psoralen pyrolysis were detected using a solid pyrolysis apparatus and synchrotron radiation vacuum ultraviolet photoionization mass spectrum (SVUV-PIMS). The pyrolytic kinetics of psoralen was also studied by calculating its initial pyrolytic route in quantum chemistry. According to the findings with SVUV-PIMS, three pyrolytic products were observed, CO, C9H6O and C10H6O2. Theoretically, three fragment pathways were calculated for psoralen, in which the major primary decomposition route was de-CO, and the major secondary decomposition reaction was de-CO reaction of de-CO products.
在本研究中，使用固体热解装置和同步辐射真空紫外光电离质谱（SVUV-PIMS）检测了补骨脂素的热解产物。还通过量子化学计算补骨脂素的初始热解途径，研究了其热解动力学。根据SVUV-PIMS的研究结果，观察到三种热解产物，即CO、C9H6O和C10H6O2。理论上，计算了补骨脂素的三条裂解途径，其中主要的初级分解途径是脱CO，主要的次级分解反应是脱CO产物的脱CO反应。
