Wenn Elektronen Walzer tanzen

Rechts- und linkshändige Moleküle lassen sich mit Hilfe kurzer Laserpulse auseinanderhalten

(PresseBox) (Berlin, )
Die Identifikation rechts- und linkshändiger Moleküle ist entscheidend für viele Anwendungen in der Chemie und Pharmazie. Ein internationales Forscherteam (CELIA-CNRS/INRS/Max-Born-Institut/SOLEIL) hat nun ein neues originelles und hochempfindliches Verfahren vorgestellt, mit dem sich die Händigkeit von Molekülen um ein Vielfaches besser bestimmen lässt als mit bisherigen Methoden. Mit Hilfe extrem kurzer Laserpulse bringen die Forscher Elektronen in Molekülen zum Schwingen und können so den Drehsinn der Moleküle bestimmen. Die Forschungsergebnisse sind in „Nature Physics“ erschienen.
