RAMAN SPECTROSCOPY OF MASS-SELECTED METAL CLUSTERS IN AGRON MATRICES

This book emphasizes the importance of fundamentals and applications of Raman and Abosorption spectroscopy for the transition metal clusters,the desire to understand the frontier between molecular chemistry and solid state physics, as well as to gain new insight into the chemical properties of the metal surfaces used in heterogeneous catalysis is one of the motivations for the extensive work done on metal clusters. Absorption and Resonance Raman spectroscopy is employed to interrogate mass-selected metal clusters in argon matrices.Neutralized cluster samples are interrogated by absorption, excitation, fluorescence and Raman spectroscopy. The information about the geometry, electronic and vibrational structures, dissociation energies and force constants are determined from resonance Raman spectroscopy, absorption and Raman excitation profiles which turned out to be a very useful and fruitful method to assign all the optical transitions involved in each metal clusters.
