Pseudo-Jahn-Teller origin of the low barrier hydrogen bond in N2H7+ [PDF]

open access: bronzeThe Journal of Chemical Physics, 2008
The microscopic origin and quantum effects of the low barrier hydrogen bond (LBHB) in the proton-bound ammonia dimer cation N2H7+ were studied by means of ab initio and density-functional theory (DFT) methods. These results were analyzed in the framework of vibronic theory and compared to those obtained for the Zundel cation H5O2+.

Solid‐State 17O NMR Reveals Hydrogen‐Bonding Energetics: Not All Low‐Barrier Hydrogen Bonds Are Strong

open access: closedAngewandte Chemie International Edition, 2017
AbstractWhile NMR and IR spectroscopic signatures and structural characteristics of low‐barrier hydrogen bond (LBHB) formation are well documented in the literature, direct measurement of the LBHB energy is difficult. Here, we show that solid‐state 17O NMR spectroscopy can provide unique information about the energy required to break a LBHB.

Short hydrogen bonds in the catalytic mechanism of serine proteases [PDF]

open access: yesJournal of the Serbian Chemical Society, 2008
The survey of crystallographic data from the Protein Data Bank for 37 structures of trypsin and other serine proteases at a resolution of 0.78–1.28 Å revealed the presence of hydrogen bonds in the active site of the enzymes, which are formed between the ...
