Journal ArticleDOI

Hans-Heinrich Limbach,Mariusz Pietrzak,Shasad Sharif,Peter M. Tolstoy,Peter M. Tolstoy,Ilya G. Shenderovich,Ilya G. Shenderovich,S. N. Smirnov,Nikolai S. Golubev,Gleb S. Denisov +9 more
TL;DR: In this paper, an empirical correction factor was derived from the known experimental structure of a very strong OHN hydro-gen bond between pentachlorophenol and 4-methylpyridine, determined by the neutron diffraction method.
Journal ArticleDOI
Empirical corrections for anharmonic zero-point vibrations of hydrogen and deuterium in geometric hydrogen bond correlations
Hans-Heinrich Limbach,Mariusz Pietrzak,Hans Benedict,Peter M. Tolstoy,Peter M. Tolstoy,Nikolai S. Golubev,Gleb S. Denisov +6 more
TL;DR: In this paper, empirical corrections for anharmonic ground-state vibrations of hydrogen and deuterium in the hydrogen bridges A-L⋯B, L=H, D are introduced into the geometric hydrogen bond correlation analysis based on the empirical Pauling valence bond orders.
Journal ArticleDOI
1H/2H NMR studies of geometric H/D isotope effects on the coupled hydrogen bonds in porphycene derivatives.
TL;DR: The vicinal effects indicate a cooperative coupling of the two hydrogen bonds which may favor a concerted double proton-transfer mechanism and the primary H/D isotope effects on the chemical shifts give information about the primary, secondary, and vicinal geometric isotopes effects of theTwo inner hydrogen bonds of porphycenes.
Journal ArticleDOI
Geometric H/D Isotope Effects and Cooperativity of the Hydrogen Bonds in Porphycene
TL;DR: The hydrogen bonds are cooperative, that is, both expand simultaneously even in the case of an asymmetric isotopic substitution, and the theoretical predictions compare favorably with NMR chemical-shift data.
Journal ArticleDOI
Symmetrization of cationic hydrogen bridges of protonated sponges induced by solvent and counteranion interactions as revealed by NMR spectroscopy.

TL;DR: The properties of the intramolecular hydrogen bonds of doubly (15)N-labeled protonated sponges of the 1,8-bis(dimethylamino)naphthalene (DMANH(+)) type have been studied as a function of the solvent, counteranion, and temperature using low-temperature NMR spectroscopy.
