Journal ArticleDOI
Generic Structural Relaxation in Supercooled Liquids.
Florian Pabst,Jan Philipp Gabriel,Till Böhmer,Peter Weigl,Andreas Helbling,Timo Richter,Parvaneh Zourchang,Thomas Walther,Thomas Blochowicz +8 more
TL;DR: In this paper, it was shown that the light scattering spectra of very different systems, e.g., hydrogen bonding, van der Waals liquids, and ionic systems, almost perfectly superimpose and show a generic line shape of the structural relaxation, following √ ω-1/2 at high frequencies.
Journal ArticleDOI
Intermolecular cross-correlations in the dielectric response of glycerol.
Jan Philipp Gabriel,Parvaneh Zourchang,Florian Pabst,Andreas Helbling,Peter Weigl,Till Böhmer,Thomas Blochowicz +6 more
TL;DR: In this paper, the authors proposed a method to disentangle self-from cross-correlation contributions in the dielectric spectra of glycerol using photon correlation spectroscopy.
Journal ArticleDOI
Dipole-dipole correlations and the Debye process in the dielectric response of nonassociating glass forming liquids.
TL;DR: In this article, the authors show that dipole-dipole correlations give rise to an additional process in the dielectric spectrum slightly slower than the α relaxation, which renders the resulting combined peak narrower than observed by other experimental techniques.
Journal ArticleDOI
Molecular dynamics of supercooled ionic liquids studied by light scattering and dielectric spectroscopy
TL;DR: In this paper, the authors investigated molecular dynamics of two supercooled room temperature ionic liquids above of their glass transition temperature by means of dynamic light scattering and broadband dielectric spectroscopy from nanoseconds up to ≈ 10 5 s.
Journal ArticleDOI
Local dielectric response in 1-propanol: α-relaxation versus relaxation of mesoscale structures.
Peter Weigl,Daniel Koestel,Florian Pabst,Jan Philipp Gabriel,Thomas Walther,Thomas Blochowicz +5 more
TL;DR: The notion that the transiently bound chain structures lead to a strong cross-correlation contribution in macroscopic dielectric experiments, to which both light scattering and TSD are insensitive, is supported due to its local character and the former due to the molecular optical anisotropy being largely independent of the OH bonded suprastructures.
