Cover Picture Shun-ichi Ishiuchi, Makoto Sakai, Yuji Tsuchida, Akihiro Takeda, Yasutake Kawashima, Masaaki Fujii,* Otto Dopfer,* and Klaus M$ller-Dethlefs* 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.
