| 摘 要： | 利用同步辐射(SR)作为真空紫外光源,结合超声分子束装置,可从分子反应动力学的角度对各种分子及小团簇在全波长范围内进行光电离和光离解研究.例如:通过光电离质谱对各种反应产物进行认定;结合光电离效率曲线(PIE)测定分子及团簇的电离能,确定能级结构.本文报导了对C_2H_3Cl 在50—140nm 波长范围内进行光电离研究的初步结果.我们用四极质谱测量了各种离子碎片的光电离谱,讨论了该分子的单光子电离的反应通道.1 实验

| Abstract: | The photoionization curves for vinychloride and its abundant fragment ions,es-pecially(C_2H_3)~+and(C_2H_2)~+,have been measured with synchrotron radiation in thephoton energy range from 8-20eV on the photochemistry station at HESYRL.Thestructure of the photoionization efficiency curves(PIE)for(C_2H_3)~+and(C_2H_2)~+were firstly exhibited and explained by the vertical ionization potentials in terms ofdifferent ionization processes. |
