Observation of charge migration in amino acids

摘要: Electron transfer is a fundamental process in biochemistry, which triggers number of biochemical processes such as photosynthesis, cellular respiration and electron transport along DNA [1]. It has been recognized that the evolution many biological strictly related to ultrafast time scale corresponding dynamics. With advent attosecond technology, it was proposed track control this dynamics real time. Indeed, occurring biomolecule after sudden ionization can be driven by purely electronic effects charge migration (CM) from one end molecule other back theoretically predicted occur within ranging few-femtoseconds down hundreds-attoseconds [2].
