Fundamental Properties of the CH···O Interaction: Is It a True Hydrogen Bond?
Ab initio calculations are used to analyze the CH···O interaction between FnH3-nCH as proton donor and H2O, CH3OH, and H2CO as acceptor. The interaction is quite weak with CH4 as donor but isExpand

Strength of the CαH··O Hydrogen Bond of Amino Acid Residues*
Although the peptide CαH group has historically not been thought to form hydrogen bonds within proteins, ab initio quantum calculations show it to be a potent proton donor. Its binding energy to aExpand
