项目摘要
Within this project studies of molecular chirality will be performed within the frame of fs-laser ionization employing circularly polarized light. More specifically the circular dichroism in photoionization yields (PICD) as well as the photoelectron circular dichroism (PECD) will be investigated for selected target molecules (limonene, glycidol and 3-methylcyclopentanone) as a function of the wavelength in the UV/VIS and as the function of the spectral phase of the laser pulses. Ultimately these two experiments will be combined in photoelectron-photoion-coincidence experiment (PEPICO_CD) employing a high-repetition fs-laser system.The project aims at resolving apparent discrepancies existing between current PICD and PECD studies. By performing a photoelectron-photoion-coincidence experiment we will elucidate whether the two effects PICD and PECD, which are based on different selection rules, are simply additive or depend on each other. We expect that the results of this research will contribute to improving future applications of fs-laser ionization mass spectrometry in the investigation of chirality properties in chemical analysis.
在本计画中,分子手性的研究将在飞秒激光圆偏振光电离的框架下进行。更具体地说,在光电离产率(PICD)以及光电子圆二色性(PECD)的圆二色性将被调查选定的目标分子(柠檬烯,缩水甘油和3-甲基环戊酮)作为在UV/维斯的波长的函数,并作为激光脉冲的光谱相位的函数。最后,这两个实验将结合在一个高重复频率飞秒激光系统中进行光电子-光离子-符合实验(PEPICO_CD),旨在解决目前PICD和PECD研究中存在的明显差异。通过光电子-光离子-符合实验,我们将阐明基于不同选择规则的两种效应PICD和PECD是简单相加还是相互依赖。我们期望本研究的结果将有助于提高未来的应用飞秒激光电离质谱在化学分析中的手性性质的调查。
