Laser control of ultrafast double proton transfer is investigated for a two-dimensional model for asymmetrically substituted porphycene by means of an infrared pump-dump scheme. Based on the orientation of the transition dipole moments the tautomerization control may lead to an estimated change in the Förster transfer coupling between chromophors of molecular wires of about 60%. The excitation of the degenerate E1 carbonyl stretching vibrations in dimanganese decacarbonyl using circularly
