The dynamics of vibrational wave packets excited in K2 dimers attached to superfluid helium nanodroplets is investigated by means of femtosecond pump-probe spectroscopy. The employed resonant three-photon- ionization scheme is studied in a wide wavelength range and different pathways leading to K2 + formation are identified. While the wave packet dynamics of the electronic ground state is not influenced by the helium environment, perturbations of the electronically excited states are observed. The latter reveal a strong time dependence on the timescale 3-8 ps which directly reflects the dynamics of desorption of K2 off the helium droplets.
