We investigate the differential ionization probability of chiral molecules in the strong-field regime as a function of the helicity of the incident light. To this end, we analyze the fourfold ionization of bromochlorofluoromethane (CHBrClF) with subsequent fragmentation into four charged fragments and different dissociation channels of the singly ionized methyloxirane. By resolving for the molecular orientation, we show that the photoion circular dichroism signal strength is increased by 2 orders of magnitude.

手性分子强场电离中的强差分光电圆二色性

我们研究了强电场条件下手性分子的不同电离概率与入射光的螺旋度的关系。为此，我们分析了溴氯氟甲烷（CHBrClF）的四重电离，随后将其破碎成四个带电的片断，以及单个电离的甲基环氧乙烷的不同解离通道。通过解析分子的取向，我们表明光子圆二色性信号强度增加了2个数量级。
