We apply a three-fold covariance imaging method to analyse previously acquired data [C. S. Slater et al., Phys. Rev. A 89, 011401(R) (2014)] on the femtosecond laser-induced Coulomb explosion of spatially pre-aligned 3,5-dibromo-3′,5′-difluoro-4′-cyanobiphenyl molecules. The data were acquired using the “Pixel Imaging Mass Spectrometry” camera. We show how three-fold covariance imaging of ionic photofragment recoil trajectories can be used to provide new information about the parent ion’s molecular structure prior to its Coulomb explosion. In particular, we show how the analysis may be used to obtain information about molecular conformation and provide an alternative route for enantiomer determination.

交流：激光诱发的库仑爆炸的三重协方差成像

我们应用三重协方差成像方法来分析先前获得的数据[CS Slater等。，物理修订版A 89上在空间上的预对准的3,5-二溴-3'，5'-二氟-4'-氰基联苯分子的飞秒激光诱导库仑爆炸，011401（R）（2014）]。使用“像素成像质谱”相机获取数据。我们展示了如何使用离子光碎裂后坐力轨迹的三重协方差成像来提供有关母离子库仑爆炸之前分子结构的新信息。特别是，我们展示了如何将分析用于获得有关分子构象的信息，并提供对映异构体确定的替代途径。
