Intramolecular hydrogen bonding in 1.8-dihydroxyanthraquinone, 1-aminoanthraquinone, and 9-hydroxyphenalenone studied by picosecond time-resolved fluorescence spectroscopy in a supersonic jet
Article Abstract:
The influence of structural and energetic features associated with intramolecular hydrogen bonding on the energy- and time-resolved fluorescence properties of large organic molecules were studied by determining their fluorescence excitation spectra and state-selective fluorescence lifetimes under supersonic jet conditions. The findings lead to the conclusion that fluorescence properties of these molecules are associated with a single-minimum-type potential.

Asymmetric hydrogen-bonding of the quinone cofactor in photosystem I probed by C-labeled naphtoquinones
Article Abstract:
The phylloquinone secondary acceptor functions as one electron in photosystem I (PSI). Quinone binding site and bacterial reaction centers are completed to analyze and get experimental evidence for unusual backbone H-bond strength.

Role of the solvent in comouting the 1,4-benzosemiquinone 9-tensor by the coupled-perturbed koh-sham hybrid density functional method
Article Abstract:
Neese's CPKS method is used to compute g-tensor component of the Bz SQ radical anion. Study also reveals that in all calculations the EPR-II and Aug-cc-pVTZ basis sets give similar results.
