Choreografie der Moleküle

Röntgenblitze "filmen" molekulare Schalter

(PresseBox) (Garching, )
Einem Forscherteam der Max-Planck-Institute für biophysikalische Chemie, für medizinische Forschung und für Kernphysik sowie des European XFEL, der Universität Göttingen und des Deutschen Elektronen-Synchrotrons (DESY) ist es erstmals gelungen, Freie-Elektronen-Laser-Strahlung für die Untersuchung chemischer Kristallstrukturen einzusetzen. Die Aufnahmen erfolgten mit dem Freie-Elektronen-Laser FLASH am DESY. Wie die Experimente der Wissenschaftler zeigen, lassen sich strukturelle Momentaufnahmen der Moleküle ganz ohne Artefakte abbilden - trotz hoher Intensität des Röntgenlasers.

Die Lichtblitze des 260 Meter langen Freie-Elektronen-Lasers (FEL) am Deutschen Elektronensynchrotron sind nicht nur leistungsstark, sondern auch ultrakurz: Die kürzeste erreichte Wellenlänge ist gerade einmal sieben Nanometer (millionstel Millimeter). Ultrakurz ist auch zth Yixch txw Gdbxklrtoiizftt, jji omwt eca 88 Oenyrxktewpug (wvcmqagdkkts Nixlbqsz) vkeuaho.
