Kasseler Physiker entwickeln neue Methode zur Erkennung chiraler Moleküle

(PresseBox) (Kassel, )
Physikern der Uni Kassel ist es erstmals mit Hilfe von Laserpulsen gelungen, chirale Moleküle mit hoher Empfindlichkeit nachzuweisen. Die neue Technik besitzt ein erhebliches Anwendungspotenzial in der Chemie- und Pharmaforschung.

Forscher des Fachgebiets Experimentalphysik III - Femtosekundenspektroskopie und ultraschnelle Laserkontrolle - unter der Leitung von Prof. Dr. Thomas Baumert und Prof. Dr. Matthias Wollenhaupt konnten in einem nur tischgroßen Laserexperiment Effekte im Bereich von zehn Prozent für Moleküle mit unterschiedlicher Chiralität demonstrieren. Die durchgeführten Experimente waren derart empfindlich, dass bereits an hochverdünnten Molekülen eindeutige Messsignale beobachtet werden konnten.
