Structural rearrangements and fragmentation pathways induced by a low-energy electron attachment to ethyl acetate

The phenomenon of dissociative electron attachment to ethyl acetate is investigated within the 1 to 13 eV energy region. The recorded yields of various fragment anions within the above-mentioned energy range reveal a diverse array of products with six different mass numbers. Examples include (${M\ensuremath{-}\mathrm{H})}^{\ensuremath{-}}$, ${\mathrm{CH}}_{3}{}^{\ensuremath{-}}$, ${\mathrm{C}}_{2}{\mathrm{H}}_{5}{\mathrm{O}}^{\ensuremath{-}}$, ${\mathrm{CH}}_{3}{\mathrm{CO}}^{\ensuremath{-}}$, ${\mathrm{CH}}_{2}{\mathrm{CHO}}^{\ensuremath{-}}$, and ${\mathrm{CH}}_{3}{\mathrm{COO}}^{\ensuremath{-}}$, formed through the fracture of single bonds. Interestingly, the generation of other fragments, such as ${\mathrm{HCCO}}^{\ensuremath{-}}$, suggests a more intricate structural rearrangement of the nuclei, adding a layer of complexity to the observed dissociation dynamics.
