The cover picture shows a methanol molecule interacting with an acid site (AlOH) in the cage of a silicon-rich sodalite (Si = blue, O = red, Al = yellow, C = green, H = white). The spheres representing the alcohol and the acidic site have been enlarged by a factor of two for reasons of clarity, and the methanol molecule is surrounded by an isosurface of its electron density. The dynamic behavior of the alcohol at finite temperature is crucial for the understanding of many catalytic processes. These state-of-the-art computer simulations that provide new insights into the microscopic mechanism of the interaction of methanol with molecular sieves are discussed by E. Nusterer, P. E. Blöchl, and K. Schwarz on p. 175ff.
