Frontiers in Chemistry, 2014 Hydrogen-bonds structure in poly(2-hydroxyethyl methacrylate) (PHEMA) were investigated by means of temperature-dependent infrared (IR) spectroscopy. Spectral variations involved with the OH•••OH and C=O•••HO types of hydrogen-bonds were found around the

H2XP:OH2 Complexes: Hydrogen vs. Pnicogen Bonds
Crystals, 2016 A search of the Cambridge Structural Database (CSD) was carried out for phosphine-water and arsine-water complexes in which water is either the proton donor in hydrogen-bonded complexes, or the electron-pair donor in pnicogen-bonded complexes.

Do Hydrogen Bonds Influence Excitonic Splittings?
CHIMIA, 2016 The excitonic splitting and vibronic quenching of the inversion-symmetric homodimers of benzonitrile, (BN)2, and meta-cyanophenol, (mCP)2, are investigated by two-color resonant two-photon ionization spectroscopy.

Diethyl [(4-bromophenyl)(5-chloro-2-hydroxyanilino)methyl]phosphonate
Acta Crystallographica Section E, 2009 In the title compound, C17H20BrClNO4P, intermolecular C—H...O and N—H...O hydrogen bonds form centrosymmetric R22(10) dimers linked through O—H...O intermolecular hydrogen bonds, which form centrosymmetric R22(16) dimers ...

Chemistry - An Asian Journal, 2019 Hydrogen bonds are a complex interplay between different energy components, and their nature is still subject of an ongoing debate. In this minireview, we therefore provide an overview of the different perspectives on hydrogen bonding.

N+-C-H···O Hydrogen bonds in protein-ligand complexes
Scientific Reports, 2019 In the context of drug design, C-H···O hydrogen bonds have received little attention so far, mostly because they are considered weak relative to other noncovalent interactions such as O-H···O hydrogen bonds, π/π interactions, and van der Waals ...

Nature of the Hydrogen Bond Enhanced Halogen Bond [PDF]
Molecules, 2021 The factors responsible for the enhancement of the halogen bond by an adjacent hydrogen bond have been quantitatively explored by means of state-of-the-art computational methods. It is found that the strength of a halogen bond is enhanced by ca. 3 kcal/mol when the halogen donor simultaneously operates as a halogen bond donor and a hydrogen bond ...
