Substrate-Adsorbate Coupling in CO-Adsorbed Copper.
The vibrational properties of carbon monoxide adsorbed to the copper (100) surface are explored within density-functional theory. Atoms of the substrate and adsorbate are treated on an equal footing in order to examine the effect of substrate–adsorbate coupling. This coupling is found to have a significant effect on the vibrational modes, particularly the in-plane frustrated translation, which ...
متن کاملAdsorption of reactive particles on a random catalytic chain: an exact solution.
We study equilibrium properties of a catalytically activated annihilation A+A-->0 reaction taking place on a one-dimensional chain of length N (N--> infinity ) in which some segments (placed at random, with mean concentration p) possess special, catalytic properties. Annihilation reaction takes place as soon as any two A particles land onto two vacant sites at the extremities of the catalytic s...
متن کاملOn Random Binary Trees
A widely used class of binary trees is studied in order to provide information useful in evaluating algorithms based on this storage structure. A closed form counting formula for the number of binary trees with n nodes and height k is developed and restated as a recursion more useful computationally . A generating function for the number of nodes given height is developed and used to find the a...
متن کاملAmmonia adsorption on iron phthalocyanine on Au(111): influence on adsorbate-substrate coupling and molecular spin.
The adsorption of ammonia on Au(111)-supported monolayers of iron phthalocyanine has been investigated by x-ray photoelectron spectroscopy, x-ray absorption spectroscopy, and density functional theory calculations. The ammonia-induced changes of the x-ray photoemission lines show that a dative bond is formed between ammonia and the iron center of the phthalocyanine molecules, and that the local...
متن کاملAdsorbate Geometry Distinction in Arenethiols by Ion/Surface Reactive Collisions
ions, the 1,2-BDMT monolayer on Au also appears to show contributions from CnSHm ions. The isomeric BDMT chemisorbates on Au each display a maximum of eight carbon atom abstractions, whereas when they are assembled on Ag, abstraction of hydrocarbon groups with a maximum of fourion of hydrocarbon groups with a maximum of four carbons by pyridine is observed. The intensity of the peaks due to the...
