摘要：
A comprehensive theory of the adsorption of CO on Ru(0001) is developed to describe equilibrium properties and the adsorption and desorption kinetics. The basis is a multi-site lattice gas model with site exclusion and lateral interactions between CO molecules out to second neighbour unit cells. The theory reproduces the coverage and temperature dependence of coverage isobars, heat of adsorption, structural data, sticking coefficients, and isothermal and temperature-programmed desorption rates in a consistent manner.
