Journal ArticleDOI
Breakdown of the stokes-einstein relation in supercooled liquids
Gilles Tarjus,Daniel Kivelson +1 more
TL;DR: In this article, the Stokes-Einstein and Stokes Einstein-Debye relations hold well in nonsupercooled liquids; however, sizeable deviations from the former appear in supercooled liquid, leading to a decoupling of translational diffusion from viscosity and reorientational relaxation.

Rotational Dynamics of Coumarin 153: Time-Dependent Friction, Dielectric Friction, and Other Nonhydrodynamic Effects
TL;DR: In this paper, the rotational anisotropy decays of coumarin 153 are generally nonexponential as a result of the non-Markovian nature of the friction on its rotational motion.
Journal ArticleDOI
Breakdown of Kramers theory description of photochemical isomerization and the possible involvement of frequency dependent friction
TL;DR: In this article, the authors present new data on the ground state isomerization rate of DODCI and compare their results to previously obtained excited state data, finding that the one-dimensional Kramers expression does not fit the data over the whole viscosity range when the friction is measured by either the overall rotation time or the solvent viscosities.

Photochemical isomerization in solution. Photophysics of diphenyl butadiene
TL;DR: In this article, the radiative and nonradiative decay rates of diphenyl butadiene in hydrocarbon and polar solvents were examined as a function of temperature and pressure.
Journal ArticleDOI
Nanostructural organization and anion effects on the temperature dependence of the optical Kerr effect spectra of ionic liquids.
TL;DR: The temperature independence of the OKE spectra and the temperature dependence of the bulk density in [C(5)mim]Br and [C (5)Mim][PF(6)] suggest that there are inhomogeneities in the densities of these liquids.
