利用同步辐射真空紫外单光子电离技术和分子束取样,研究了低压下苯的介质阻挡放电产生的低温等离子体.通过测量光电离质谱和光电离效率谱,鉴别了等离子体放电过程中产生的一系列自由基和中性分子的化学结构.
Non-thermal plasma produced by a dielectric barrier discharge (DBD) of benzene at low pressure was investigated by tunable synchrotron radiation single-photon ionization and molecular-beam mass spectrometry techniques. A series of free radicals and the neutral molecules were identified by measuring of photoionization mass spectrometry combined with photoionization efficiency spectra.
