摘要
探索低能电子诱导的分子碎裂动力学，为了解射弹与目标之间复杂的相互作用提供了令人信服的见解。在本研究中，我们研究了电子附着在乙酸乙酯上的解离现象。在 1 到 13 eV 的入射电子能量范围内，记录到的各种碎片阴离子的产率显示了具有六种不同质量数的多种产物。例如，通过单键断裂形成的 (M$-$H)$^-$、CH$_3^-$、C$_2$H$_5$O$^-$、CH$_3$CO$^-$、CH$_2$CHO$^-$ 和 CH$_3$COO$^-$。有趣的是，其他碎片（如 HCCO$^-$）的产生表明原子核发生了更为复杂的结构重排，从而为所观察到的解离动力学增加了一层复杂性。
Structural rearrangements and fragmentation pathways induced by a low-energy electron attachment to ethyl acetate
Exploring the molecular fragmentation dynamics induced by low-energy
electrons offers compelling insights into the complex interplay between the
projectile and target. In this study, we investigate the phenomenon of
dissociative electron attachment to ethyl acetate. The recorded yields of
various fragment anions within an incident electron energy range of 1 to 13 eV
reveal a diverse array of products with six different mass numbers. Examples
include (M$-$H)$^-$, CH$_3^-$, C$_2$H$_5$O$^-$, CH$_3$CO$^-$, CH$_2$CHO$^-$,
and CH$_3$COO$^-$, formed through the fracture of single bonds. Interestingly,
the generation of other fragments, such as HCCO$^-$, suggests a more intricate
structural rearrangement of the nuclei, adding a layer of complexity to the
observed dissociation dynamics.
