摘要：

Identifying the pathways and timescales of excitation energy transfer is a central goal in the design of artificial light harvesting systems and energy transporting wires. Coherent femtosecond two-dimensional electronic spectroscopy provides this information for a molecular nanotube by correlating excitonic absorption and emission frequencies at various delay periods. In combination with simulations based on a coupled electronic oscillator model the experiments reveal the electronic coupling pattern and show the various energy transfer pathways into the lowest accessible state.
