Abstract
Interest in the electronic structure and properties of small atomic and molecular clusters has risen sharply recently. These aggregates play key roles in diverse fields such as heterogeneous catalysis, homogeneous nucleation, the photographic process, upper atmospheric phenomena and chemical processes in interstellar media. By using a modified matrix isolation system we have been, able to generate and trap metallic (and non-metallic) clusters in a variety of environments including solid rare gases and solid paraffins. In this manner we have been able to see both the progress of the electronic spectrum towards that of the bulk material as well as the approach of the vibrational spectrum of molecules bonded to metal clusters towards that of the chemisorbed molecule. Results with copper, nickel and palladium will be presented.
