Description:
In the past decade, attosecond technology has opened up the investigation of ultrafast electronic processes in atoms, simple molecules, and solids. Here, we report the application of isolated attosecond pulses to prompt ionization of the amino acid phenylalanine and the subsequent detection of ultrafast dynamics on a sub-4.5-femtosecond temporal scale, which is shorter than the vibrational response of the molecule. The ability to initiate and observe such electronic dynamics in polyatomic molecules represents a crucial step forward in attosecond science, which is progressively moving toward the investigation of more and more complex systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calegari, F -- Ayuso, D -- Trabattoni, A -- Belshaw, L -- De Camillis, S -- Anumula, S -- Frassetto, F -- Poletto, L -- Palacios, A -- Decleva, P -- Greenwood, J B -- Martin, F -- Nisoli, M -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):336-9. doi: 10.1126/science.1254061.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Photonics and Nanotechnologies (IFN)-Consiglio Nazionale delle Ricerche (CNR), Piazza Leonardo da Vinci 32, 20133 Milano, Italy. ; Departamento de Quimica, Modulo 13, Universidad Autonoma de Madrid, Cantoblanco 28049 Madrid, Spain. ; Department of Physics, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milano, Italy. ; Centre for Plasma Physics, School of Maths and Physics, Queen's University, Belfast BT7 1NN, UK. ; IFN-CNR, Via Trasea 7, 35131 Padova, Italy. ; Dipartimento di Scienze Chimiche e Farmaceutiche, Universita di Trieste and CNR-Istituto Officina dei Materiali, 34127 Trieste, Italy. ; Departamento de Quimica, Modulo 13, Universidad Autonoma de Madrid, Cantoblanco 28049 Madrid, Spain.
