摘要
用合肥国家同步辐射实验室光化学站的实验装置研究了苯分子的光电离质谱，从所得光电离效率话精确地走出了苯分子的电离势及苯离子的出现势，并首次报道了三个苯离子的离解能。
The photoionization mass spectra and photoionization efficiency spectra were studied by using synchrotron radiation at the Photochemistry station of Hefei National Synchrotron Radiation laboratory. The ionization potential of benzene and appearance potential of its main fragments are obtained from photoionization efficiency spectra. The dissociation energies of benzene ions are reported for the first time. The obtained value of ionization potential of benzene is in good agreement with the theoretical values and the previous ones. From this fact, it can be seen that the photoionization by synchrotron radiation is a precise and efficient photoionization method.
