Summary on Grant Application Form |
|
A pulsed arc vaporisation source has been coupled to an ion trap for the purposes of generating and trapping clusters from refractory materials. Small size-selected metal and semiconductor clusters will be held in the trap in the presence of a source of volatile organic molecules, such as methanol, acetone etc. Following the adsorption of a molecule onto the surface of a cluster, the combined species were isolated and subjected to multiphoton infrared excitation using low power laser radiation. From the pattern of behaviour identified in previous experiments on metal atom - molecule complexes, it is expected that some metal clusters will promote reactivity following IR excitation, whilst in others, the metal - molecule bond will break. A theoretical model has been developed to account for all the processes taking place in the trap, and ion fragmentation patterns can be accurately predicted.Since both IR lasers are line-tuneable, it will be possible to record absorption profiles for the metal cluster - molecule complexes, and these can be compared with those measured for the same molecules on bulk surfaces using LEED.
