The bond rearrangement channel is very small but not significantly slower than other fragmentation processes

H2+ + O

≈ 0.9 %

OH + H+

•   Dissociation to  OH + H+    is energetically favored    over  H2+ + O •   In addition, the OH + H+    dissociation path is    kinematically favored

O + H2+

O-H bonds held equal
