Time-resolved dissociation dynamics of the [CpFe(CO)(2)](2) molecule in the gas phase

The photodissociation dynamics of [CpFe(CO)(2)](2) in the gas phase is inve stigated with femtosecond time resolution. Using femtosecond laser pulses a t 400 and 800 nm, the parent molecular ion and corresponding fragment ions are observed with a reflectron time-of-flight (TOF) spectrometer. Employing the pump-probe technique their ionization transients are measured. We find that the photodissociation dynamics of this molecule having two different metal-ligand bonds and one metal-metal bond is dominated by the dynamics of three different intermediate states.
