Query: Laser-Driven Localization of Collective CO Vibrations in Metal-Carbonyl
  Complexes   Using the example of a cobalt dicarbonyl complex it is shown that two
perpendicularly polarized IR laser pulses can be used to trigger an excitation
of the delocalized CO stretching modes, which corresponds to an alternating
localization of the vibration within one CO bond. The switching time for
localization in either of the two bonds is determined by the energy gap between
the symmetric and asymmetric fundamental transition frequencies. The phase of
the oscillation between the two local bond excitations can be tuned by the
relative phase of the two pulses. The extend of control of bond localization is
limited by the anharmonicity of the potential energy surfaces leading to wave
packet dispersion. This prevents such a simple pulse scheme from being used for
laser-driven bond breaking in the considered example.
