A simple picture of x-ray emission of condensed phase water
(English)Manuscript (preprint) (Other academic)
We apply the Kramers-Heisenberg formula to a one-dimensional model of the water dimer to discuss vibrational interference in the x-ray emission spectrum of the donor molecule for which the core-ionized potential energy surface is known to be dissociative. The isotope effect is discussed and connections are made to recent experimental data on liquid water in terms of asymmetrical broadening of the 1b1 spectral features. A long core-hole life time leads to decay from Zundel-like, fully delocalized vibrational states in the intermediate potential without involvement of a specific dissociated component.
