“…The resonance field B res is determined by the hyperfine coupling constants of the radical; these coupling constants are, among other factors, sensitive to the polarity of the surroundings, and B res is shifted to higher values with increasing polarity. [15] The polarity of the local environment and thus the location in the LLC is determined by comparing B res in the LLC with the values in a [14,15] We present the first application of ALC-mSR to a chiral nematic LLC phase to reveal new aspects of the still unexplained chiral induction mechanism in nematic LLC phases, and begin with the actual location and reorientation dynamics of chiral dopants. ALC-mSR cannot directly measure a chiral, that is, a mathematically pseudoscalar quantity.…”

“…The ALCmSR technique [14,15] involves the formation of a radical by the addition of muonium, Mu, a light hydrogen isotope (m H = 9 m Mu ) with a positive muon m + as the nucleus, to an unsaturated bond (Scheme 1). The time-integrated muon spin polarization, which is proportional to the muon decay asymmetry A, is measured as a function of an external magnetic field.…”

“…Bei der ALCmSR [14,15] wird durch Addition von Myonium (Mu), einem leichten Wasserstoffisotop (m H = 9 m Mu ) mit einem positiven Myon (m + ) als Kern, an eine ungesättigte Bindung ein Radikal gebildet (Schema 1). Gemessen wird das Zeitintegral über die Myonenspinpolarisation, die proportional zur Asymmetrie A Abbildung 1.…”

“…B. in einer Micelle. [14,15] Gegenstand dieser Arbeit ist die erste Anwendung von ALC-mSR auf eine lyotrope chiral-nematische Phase, um neue Aspekte des noch nicht aufgeklärten Mechanismus der chiralen Induktion zu erhalten. Ausgangspunkte der Untersuchungen sind die Aufklärung des Aufenthaltsorts und der Reorientierungsdynamik des chiralen Dotierstoffes.…”
