  • Investigating molecular fragmentation mechanisms and the kinetic energy distributions of fragments provides crucial insights into their roles in plasma physics, radiation-induced damage in biological tissues, and interstellar chemistry. In this study, we conducted collision experiments between 3 keV/u Ar8+ ions and CH3F molecules using a cold target recoil ion momentum spectrometer. We focused on the three-body fragmentation channel H+ + CH2+ + F+ resulting from C-F and C-H bond cleavage in CH3F3+ ions, and measured the three-dimensional momentum vectors of all fragment ions. The fragmentation mechanism involved was analyzed using ion-ion kinetic energy correlation spectra, Newton diagrams, Dalitz plots and other correlation spectra.
    Our results reveal two distinct dissociation mechanisms for the H+ + CH2+ + F+ channel, i.e., concerted and sequential fragmentation, with the former one being dominant. In the sequential fragmentation process, H+ and the intermediate CH2F2+ are firstly formed, followed by further fragmentation of the intermediates into CH2+ and F+. No sequential pathways involving HF2+ or CH32+ intermediates were identified. Furthermore, we observed two types of concerted fragmentation processes with different dynamical characteristics, suggesting that hydrogen atoms in CH3F3+ may occupy different chemical environments. This phenomenon could originate from either molecular isomerization producing different structural geometries or the Jahn-Teller effect leading to inequivalent C-H bonds. This study reveals the three-body dissociation dynamics of CH3F3+ induced by highly charged ion collisions, highlighting the significant role of the Jahn-Teller effect or molecular isomerization in the ionic dissociation of polyatomic molecules.
