The chapter discusses ferromagnetic bonding in no‐pair clusters of alkali and coinage metals, n+ 1 M n (M=Li, Na, Cu, Ag, and Au). These clusters have maximum spin and not even a single electron pair. It is shown that the bonding energy per atom, D e /n, exhibits a strongly nonadditive behavior; it grows rapidly with the cluster size and converges to values of 12–19 kcal mol −1 for

Chemisorption of tertiary phosphines on coinage and
20.12.1998· Coinage metal surfaces are easier to study as they have less adsorbed oxygen and hydrogen than the platinum and palladium surfaces, and larger reflectance indices which give a more favorable signal to noise (S/N) ratio. Interfacial phenomena on metal surfaces where small organic molecules are involved are normally very difficult to study because of the small amounts present on

Nucleation rates for the condensation of monovalent
We show that consideration of both cluster growth and magic numbers are necessary to accurately calculate nucleation rates for the condensation of alkali and coinage metal vapors. The effects are not additive. Rates calculated using the modified theory differ up to several orders of magnitude from typical classical calculations. Calculated rates compare favorably with experimental nucleation
