Solvent influence on photoisomerization dynamicsa)

Abstract

The rate constants of the nonradiative decay process of the excited singlet state of trans-stilbene and trans-1,1′-biindanylidene (‘‘stiff ’’ stilbene) were measured in liquid n-alkanes at room temperature. These data were compared with the two models for isomerization in condensed phases proposed by Kramers and by Grote and Hynes. For trans-stilbene, the agreement with Kramers’ model was unsatisfactory, whereas better agreement was obtained with Grote and Hynes’ model. The data for stiff stilbene agreed well with Kramers’ model in the Smoluchowski limit. These results were explained in terms of the shape of the potential energy barrier which separates the trans from the twisted configuration of the excited singlet state of these molecules. It is suggested that the deviation between theory and experiment is a result of a qualitative difference in the microscopic solvent–solute collisional interaction when the solvent molecules are longer than stilbene. The best fit of theory to experiment for trans-stilbene requires the use of an unphysically low (8 cm−1) frequency for the top of the barrier to isomerization.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
