Bond rearrangement forming H-H+ bond upon
dissociation of transient
|
water molecular ion
|
|
|
|
|
Bond rearrangement occurs in single and multiple ionization
|
|
|
|
|
An isotopic effect has been observed in single and double
ionization,
|
|
|
bond rearrangement is more probable for less massive isotopes.
|
|
|
|
|
The data suggests that bond-rearrangement is approximately a
|
|
|
|
constant fraction of each ionization level
|
|
|
|
|
A sudden mechanism is suggested in which the matching of the
|
|
|
initial and final states are the key factor
