Mixed van der Waals clusters of CrCO6 and methanol, generated in a pulsed free-jet expansion of seeded helium, are irradiated by strongly focused UV laser pulses, corresponding to intensities on the order of 10 12 to 10 13 W cm2. Photoions created via multiphoton dissociation MPD and ionization MPI of these neutral clusters are analyzed by time-of-flight mass spectrometry. We find that the multiphoton dissociation and ionization dynamics of CrCO6 within van der Waals clusters are quite unusual in comparison to those of the naked molecule, since the observed photoion yields are highly wavelength dependent, and since complete ligand stripping does not appear to dominate the photophysics in the neutral ladder.
