摘要：

Multicolour near-infrared femtosecond experiments of a genetically modified bacterial reaction centre show that the phase of two excited-state vibrational modes is conserved for a period of picoseconds over a large range of temperatures. The direct visualization of low-frequency nuclear vibrations in this protein, which is embedded in its natural membrane, implicates coherent nuclear motion in the primary electron transfer reaction in functional reaction centres.
