✦ Synopsis

The vibrational excitation of H 2 produced in the reaction between gas-phase and chemisorbed H atoms on a tungsten surface is studied by use of classical trajectory procedures. In small and intermediate-impact parameter (b) collisions, the reaction probability P(b) is large, and a major fraction of the available energy goes into vibrational excitation of H 2. Gas atoms approaching the surface with b close to the H 2 bond distance are particularly efficient in H 2 formation. In large, b collisions, both P(b) and vibrational excitation are inefficient. Such a decrease in P(b) and vibrational excitation with increasing b produces a population inversion. The reaction dynamics and distribution of reaction times are discussed in detail.

Vibrationally excited NO molecules scattered from a cleaved graphite surface show rotational state populations and rotational accommodation identical to those of ground-state incoming molecules. The survival probability of the vibrational state is found to vary between 75 and 95%, depending on the s

The "bottom-up" construction of functional structures relies on the sophisticated interplay between individual structural units. [1][2][3] In most cases, the assembly of these building blocks is based on noncovalent interactions that shape extended supramolecular entities in variable dimensions. [4]
