“…A theme throughout previous studies of bond rearrangement [8,11,14,22,23,[26][27][28][39][40][41][42] has been that the primary initiating step is the stimulation of bending modes in the triatomic molecule. With this background, it is not surprising that the bent water molecule has the highest bond rearrangement branching ratio of the molecules examined in this study.…”

“…Despite the increasing attention devoted to these processes, so far most studies have focused on a single molecular species and have occurred under an assortment of experimental conditions. For example, the initiating ioniza-tion mechanism in previous bond rearrangement studies has variously included single [8,11,[37][38][39][40][41][42] and multiple photons [5,22,26,27,43] as well as electron [23,28,44] and heavy ion impact [2,7,30]. To assist in understanding these dynamics we examine bond rearrangement following ultrafast strong-field double ionization of three triatomic molecules: carbon dioxide, carbonyl sulfide and water.…”

A comparative study of bond rearrangement is reported for the double ionization of three triatomic molecules: carbon dioxide, carbonyl sulfide, and water (D2O). Specifically we study the formation of the molecular cation AC + from the edge atoms of a triatomic molecular dication ABC 2+ following double ionization by intense, short (23 fs, 790 nm) laser pulses. The comparison is made using the double ionization branching ratio of each molecule, thereby minimizing differences due to differing ionization rates. The rearrangement branching ratio is highest for water, which has a bent initial geometry, while CO2 and OCS are linear molecules. The angular distribution of O + 2 fragments arising from CO2 is essentially isotropic, while SO + from OCS and D + 2 from D2O are aligned with the laser polarization. In the CO2 and D2O cases, the angular distributions of the bond rearrangement channels are different from the angular distributions of the dominant dissociative double ionization channels CO + + O + and OD + + D + . Only the angular distribution of SO + from OCS is both aligned with the laser polarization and similar to the angular distribution of the largest dissociative channel, CO + + S + . The mixed behavior observed from the angular distributions of the different molecules stands in contrast to the relative consistency of the magnitude of the bond rearrangement branching ratio.I.

“…These factors enhance the probability of interaction among the H-atoms in NH 3 . The reports on bond rearrangement in NH 3 are very few (Locht and Momigny 1987;Senba et al 2005;Jochim et al 2009;Bhatt et al 2017) and the theoretical calculations for the electronic states involved in such rearrangement processes are scarce (Jochim et al 2009). We report in this article the formation of H 2 + and H 3 + in an NH 3 molecule under ion impact.…”

“…This results in a prompt dissociation of the molecular ion thereby reducing the possibility of comparatively slow bond rearrangement process. However, ultrafast bond rearrangement is still observed in few cases (Krishnamurthy et al 2004;Bhatt et al 2017). The rearrangement of atoms is observed under various ionizing radiations for example, by synchrotron radiation (Laksman et al 2014;Oghbaie et al 2015), by laser (Jiang et al 2010) and by ion impact (Jochim et al 2009;Bhatt et al 2017).…”

The rearrangement of H-atoms is studied in the interaction of energetic (50-2000 keV) H + and Ar q+ (q = 1, 8) ions with NH 3 . The technique of recoil ion momentum spectrometry is used to obtain various dissociation channels involved in these collision events. The variation of the relative yields of the H 2 + and H 3 + ions is obtained as a function of the interaction strength q/v, where q and v are the charge state and velocity of the projectile. It is observed that the yield of H 2 + increases with q/v of the projectile, however, H 3 + is observed only at the highest q/v.

“…[1][2][3][4][5][6][7][8] As demonstrated in several studies, both atomic and molecular dications exhibit significant bimolecular reactivity following collisions with neutral species. [9][10][11][12][13] Indeed, the lifetimes of atomic dications in planetary ionospheres are expected to be primarily determined by such collisional processes. 14 This significant dicationic reactivity suggests that dication chemistry can play a role in ionospheric processes; 15 for example, dications are proposed to be involved in the chemistry of complex molecule assembly through carbon chain-growth.…”
