Book Description
This research program explores time-resolved dynamics of molecular systems using femtosecond core level photoelectron spectroscopy. Ultrafast soft x-ray laser pump/probe studies reveal time-dependent binding energies and atomic core level-shifts in the molecules during chemical rearrangements by detecting the changes in photoelectron spectra as a function of internuclear separation in dissociative states in real time. A new apparatus introduces high order harmonics of a laser in the soft x-ray region of the spectrum. Harmonic pulses with photon energies up to 100 eV and femtosecond time resolution have been produced with excellent efficiency and pulse-to-pulse stability. Valence and core photoelectron spectra have been obtained on many neutral atoms and molecules with this apparatus.
