Journal ArticleDOI
Nature of the N-H...S hydrogen bond.
TL;DR: It was shown that the S(1)-S(0) band origin red shifts in the N-H...S hydrogen-bonded complexes correlated well with the polarizability of the acceptor rather than their proton affinity, contrary to the trend observed in most X-H…Y hydrogen-Bonded systems.
Journal ArticleDOI
Sulfur, Not Too Far Behind O, N, and C: SH···π Hydrogen Bond
TL;DR: It is found that although sulfur and its hydrides are known as poor hydrogen-bond donor/acceptors, sulfur is not too far behind oxygen, nitrogen, and carbon in regard to forming the pi-type hydrogen bonds.
Journal ArticleDOI
O-H...O versus O-H...S hydrogen bonding I: Experimental and computational studies on the p-cresol x H2O and p-cresol x H2S complexes.
TL;DR: Experimental data indicates that in the p-CR x H(2)S complex, the phenolic OH group acts as a hydrogen bond donor, and sulfur as the acceptor, and it indicates that thep-CRx H( 2)O complex was about half as strong as the p.CR x p-cresol complex, while the AIM and NBO analyses corroborate the experimental findings.
Journal ArticleDOI
Strength of NH···S Hydrogen Bonds in Methionine Residues Revealed by Gas-Phase IR/UV Spectroscopy
Himansu S. Biswal,Himansu S. Biswal,Eric Gloaguen,Eric Gloaguen,Yohan Loquais,Yohan Loquais,Benjamin Tardivel,Benjamin Tardivel,Michel Mons,Michel Mons +9 more
TL;DR: V vibrationally resolved IR NH stretch spectra of two methionine-containing dipeptides provide spectroscopic evidence for the formation of NHbackbone···S H-bonds, surprisingly strong enough to challenge the classical intrabackbone NH···O═C H- bonds.
Journal ArticleDOI
Gas-Phase Folding of a Two-Residue Model Peptide Chain: On the Importance of an Interplay between Experiment and Theory
Eric Gloaguen,B. De Courcy,Jean-Philip Piquemal,Julien Pilmé,Olivier Parisel,Rodolphe Pollet,Himansu S. Biswal,F. Piuzzi,Benjamin Tardivel,Michel Broquier,Michel Mons +10 more
TL;DR: The experimentally observed coexistence of an extended form and a folded form in the supersonic expansion was found to result from comparable Gibbs free energies for the two species under the high-temperature conditions resulting from the laser desorption technique used to vaporize the molecules.
