内容記述 |
The primary and secondary fragmentation dynamics of iodobenzene following its ionization at
120 eV were determined using three-dimensional velocity map imaging and covariance
analysis. Site-selective iodine 4d ionization was used to populate a range of excited polycationic
parent states, which primarily broke apart at the carbon-iodine bond to produce I+ with phenyl
or phenyl-like cations (CnHx+ or CnHx 2+, with n = 1–6 and x = 1–5). The molecular
products were produced with varying degrees of internal excitation and dehydrogenation,
leading to stable and unstable outcomes. This further allowed the secondary dynamics of
C6Hx 2+ intermediates to be distinguished using native-frame covariance analysis, which
isolated these processes in their own centre-of-mass reference frames. The mass resolution of
the imaging mass spectrometer used for these measurements enabled the primary and secondary
reaction channels to be specified at the level of individual hydrogen atoms, demonstrating the
ability of covariance analysis to comprehensively measure the competing fragmentation
channels of aryl cations, including those involving intermediate steps. |
