In the past few years, attosecond techniques have been implemented for the investigation of ultrafast dynamics in molecules. The generation of isolated attosecond pulses characterized by a relatively high photon flux has opened up new possibilities in the study of molecular dynamics. In this paper, we report on experimental and theoretical results of ultrafast charge dynamics in a biochemically relevant...
Electron transfer within a single molecule is the fundamental step of many biological processes and chemical reactions. It plays a crucial role in catalysis, DNA damage by ionizing radiation, photosynthesis, photovoltaics, and for switches based on molecular nano-junctions. The investigation of this process has been the subject of considerable research effort [1-2]. In this work we present the first...
We investigated the ultrafast charge-migration in the amino-acid phenylalanine. By measuring the yield of a doubly-charged ion vs. delay between a 1.5-fs XUV pulce and a 6-fs pulse, a 30-fs charge migration process was measured.
