Title:The Nickel Assisted Decomposition Of Pentanal In The Gas Phase At Various Internal Energies
Author(s):Mansell, Adam

Subject(s):Mini-symposium: Spectroscopy in Kinetics and Dynamics
Abstract:The rate constants for the dissociation of Ni$^{+}$Pentanal at various internal energies (15000 cm$^{-1}$-18800 cm$^{-1}$) were measured using a custom time of flight instrument. Clusters are generated in a large source chamber by ablating the surface of a rotating nickel rod with an excimer and entraining the ablated metal atoms in a helium gas plume slightly doped with pentanal vapor. The molecular beam enters a Wiley-Mclaren type acceleration grid, and cations are accelerated along a 1.8 meter long time-of-flight mass spectrometer (TOFMS). At the other end of the TOF is a sector and a detector. The sector allows ions of a particular kinetic energy through to the detector. If an ion breaks apart in the time it takes to reach the sector, the mass (and therefore kinetic energy) is reduced, and the sector can be set to allow these fragment ions to reach the detector (fig 2). In our experiment, the energy required to initiate the breakdown is provided by a laser pulse between 15000 cm$^{-1}$ and 18800 cm$^{-1}$.
