Journal ArticleDOI
Excited-state proton transfer reactions II. Intramolecular reactions
TL;DR: In this paper, the intrinsic processes and mechanisms of proton transfer in relation to the nature of the intramolecular hydrogen bond ring are reviewed. But the authors focus on the intrinsic process and not the mechanisms of transfer.
Journal ArticleDOI
Excited-state proton transfer reactions I. Fundamentals and intermolecular reactions
TL;DR: Theoretical models that have been proposed and applied to proton transfer reactions are reviewed in this paper, where simple models, like the Eigen model, Marcus theory and the intersecting state model, are applied to excited-state intermolecular proton transfers.
Journal ArticleDOI

TL;DR: In this paper, photoacoustic calorimetry was used to measure the quantum yields of singlet molecular oxygen production by the triplet states of tetraphenylporphyrin (TPP), ZnTPP and CuTPP in toluene, yielding values of 0.67 0.14, 0.68 0.19 and 0.03 0.07 quantum yield.
Journal ArticleDOI
Improving hierarchical cluster analysis: A new method with outlier detection and automatic clustering
TL;DR: A completely automated method to improve single linkage hierarchical cluster analysis (HCA), based on a self-consistent outlier reduction approach, followed by the building-up of a descriptive function, which allows to define natural clusters.
Journal ArticleDOI
Comparison of dissolution profiles of Ibuprofen pellets.
TL;DR: This work uses both model dependent and independent techniques to assess the difference between dissolution profiles in which ibuprofen, in the form of uncoated pellets, is used as a model drug.
