“…These results, confirming the inverse harpoon mechanism in this specially prepared system, pave the way for LRET reaction studies in various molecular systems. In particular, it will be possible to explore inverse harpooning in ionsurface reactions and in the emerging facilities for carefully prepared cold neutral-cation collisions (51)(52)(53)(54).…”

Electron-transfer reactions are ubiquitous in chemistry and biology. The electrons’ quantum nature allows their transfer across long distances. For example, in the well-known harpoon mechanism, electron transfer results in Coulombic attraction between initially neutral reactants, leading to a marked increase in the reaction rate. Here, we present a different mechanism in which electron transfer from a neutral reactant to a multiply charged cation results in strong repulsion that encodes the electron-transfer distance in the kinetic energy release. Three-dimensional coincidence imaging allows to identify such “inverse” harpoon products, predicted by nonadiabatic molecular dynamics simulations to occur between H 2 and HCOH 2+ following double ionization of isolated methanol molecules. These dynamics are experimentally initiated by single-photon double ionization with ultrafast extreme ultraviolet pulses, produced by high-order harmonic generation. A detailed comparison of measured and simulated data indicates that while the relative probability of long-range electron-transfer events is correctly predicted, theory overestimates the electron-transfer distance.

“…The HEIBT configuration simulated by Shahi et al 62 was optimized for trapping a 1 : 2 ratio of the anion and cation mass and beam energy ratio. The original rationale was to minimize as much as possible the effect of the inner trap potentials on the trajectories of the heavier ions in the outer trap.…”

“…Recently, Shahi et al, 62 proposed and simulated an alternative hybrid experimental setup for simultaneous electrostatic trapping of cation & anion beams based on the EIBT technology. 55,56 On one hand, the hybrid EIBT (HEIBT) mirror allows the trapping of a fast ion beam, while on the other hand, analogous to optical dichroic mirrors, it transmits with minimal focusing a fast beam of oppositely charged species.…”

This roadmap article highlights recent advances, challenges and future prospects in studies of the dynamics of molecules and clusters in the gas phase. It comprises nineteen contributions by scientists with leading expertise in complementary experimental and theoretical techniques to probe the dynamics on timescales spanning twenty order of magnitudes, from attoseconds to minutes and beyond, and for systems ranging in complexity from the smallest (diatomic) molecules to clusters and nanoparticles. Combining some of these techniques opens up new avenues to unravel hitherto unexplored reaction pathways and mechanisms, and to establish their significance in, e.g. radiotherapy and radiation damage on the nanoscale, astrophysics, astrochemistry and atmospheric science.
