The intermolecular binding motif of the argon atom in a phenol···Ar dimer has been
monitored on the picosecond timescale by time-resolved UV–UV(pump)–IR(probe)
ionization depletion spectroscopy. The cover picture shows the dynamic process,
which involves a shift of the initially p-bound Ar atom to a hydrophilic, hydrogenbound site. For more details, see the Communication by M. Fujii, K. M)ller-Dethlefs,
and co-workers on page 6149 ff.
Odor Perception
Humans can distinguish more than 10 000 odors. But how are these odors perceived
and processed in the brain? R. Axel and L. Buck describe their research on
page 6111 ff. and page 6128 ff., respectively, work for which they received the 2004
Nobel Prize for Medicine or Physiology.
Coordination Chains
In their Communication on page 6142 ff., T. Classen, S. Fabris, K. Kern, and coworkers describe the templating effect of the Cu(110) surface on trimesitylic acid that
results in the formation of one-dimensional metal–organic coordination chains.
Metal Nanoparticles
Porous coordination polymers such as MOF-5 readily accept MOCVD precursors, and
the stored compounds are easily reduced to give the corresponding metal
nanoparticles, as described by R. Fischer et al. in their Communication on
page 6237 ff.
