本文简要介绍了真空紫外和软X射线在自由分子光解研究中的进展。然后介绍了多离子符合动量成像和高分辨率俄歇电子-离子符合动量成像两种典型的实验装置。最后，一些个别情况下的分子解离后的核心孔创建检查，以说明如何产生的复杂的多维数据可以表示和解释。基于库仑爆炸的新的实验技术，可以直接表征的初始核运动，随后电子激发。
A brief account of the developments in photodissociation studies of free molecules by VUV and soft x-ray sources is given as an extended introduction. Then two typical experimental setups are described for multiple-ion coincidence momentum imaging and high-resolution Auger electron–ion coincidence momentum imaging. Finally, some individual cases of molecular dissociation following core-hole creation are examined, to illustrate how the complex multidimensional data produced can be represented and interpreted. The new experimental techniques based on Coulomb explosion are shown to allow direct characterization of the initial nuclear motions which follow electronic excitation.
