Mit Hilfe eines "elektrischen Prismas" haben Forscher einen Weg gefunden, um Wassermoleküle nach dem Kernspin zu sortieren. Da Wasser von fundamentaler Bedeutung im Universum ist, kann die Arbeit einer Vielzahl von Forschungsgebieten nützen, von der Biologie bis zur Astrophysik. Das Forscherteam vom Hamburger Center for Free-Electron Laser Science CFEL stellt seine Ergebnisse im Fachblatt "Angewandte Chemie" vor. Das CFEL ist eine Kooperation von DESY, Universität Hamburg und der Max-Planck-Gesellschaft.
Auf den ersten Blick ist Wasser (H2O) ein einfaches Molekül, in dem ein einzelnes Sauerstoffatom (O) an zwei Wasserstoffatome (H) gebunden ist.
