Abstract
Working the Angles on Chemical Bonding
The forces exerted by chemical bonds depend not only on the distances between atoms but also upon the angles between them.
Welker and Giessibl
(p. 444; see the cover) probed the angular dependence of the CO molecule adsorbed on top of a copper atom on an atomically flat Cu(111) surface using both atomic force microscopy and scanning tunneling microscopy (STM). Probe tips with three different tip-atom-symmetry environments were used. All three tips delivered similar STM images, but force probes revealed the angular dependence of the CO bond to the surface and provided data for a model of the changes in bond energy.
