TL;DR: T tunable femtosecond soft x-ray pulses from an x-rays free electron laser are used to reveal the dynamics of the valence hole created by strong-field ionization and to track the primary proton transfer reaction giving rise to the formation of OH.

TL;DR: In this paper, the dynamics of inner valence hole states in isopropanol were investigated using an x-ray pump-x-ray probe experiment, with site and state-specific probing of a transient hole state localized near the oxygen atom in the molecule, together with an ab initio theoretical treatment.
