Subjects
Transition metals -- Analysis, Metals -- Surfaces, Infrared spectroscopy -- Methods, Photoionization -- Observations, Molecular beams -- Observations, Scattering (Physics) -- Analysis, Chemistry
Abstract

The current status of transition metal cluster surface characteristics as influenced by size effects is presented. Determination of metal cluster structures and reactivity of bimetallic clusters are addressed.

2. Gas-phase photodissociation of (eta-5-cyclopentadienyl)Fe(CO)2R and (eta-5-indenyl)Fe(CO)2R in a molecular beam: competitive loss of alkyl radical and alkene detected by vacuum-ultraviolet ionization and time-of-flight mass spectrometry

Abstract

Vacuum ultraviolet photoionization mass spectrometry was used to determine the primary photoproducts of the photodissociation in a string of iron cyclopentadienyl compounds. The photolysis of these compounds located in a molecular beam synthesized alkyl radicals and alkene. Indenyl compound 7 was examined to study the effect of ring slippage on alkene development. The indenyl ring replaced the cyclopentadienyl ring, but the quantity of propene and propyl radical was not altered. This proved that ring slippage influences alkene growth.

3. Infrared spectra of gas-phase V(super +)-(benzene) and V(super +)-(benzene)(sub 2) complexes

Author

Heijnbergen, D. van, Helden, von G., Meijer, G., Maitre, P., and Duncan, M.A.

Subjects
Molecular beams -- Observations, Benzene -- Chemical properties, Benzene -- Research, Benzene -- Atomic properties, Infrared spectroscopy -- Usage, Chemistry
Abstract

Laser vaporization helps in producing V(C6H6)(sub 1,2) complexes in a molecular beam. Efficient one-photon ionization also occurs for both complexes at this wavelength.
