      Floquet analysis for vibronically modulated electron tunneling 

      Carias, H.; Beratan, David N.; Skourtis, Spiros S. (2011)
      Electron tunneling provides the primary reaction channel for electron transfer (ET) in many molecular systems. The analysis of such systems therefore requires the consideration of electronic coherence and interference ...
