Communication: Frequency shifts of an intramolecular hydrogen bond as a measure of intermolecular hydrogen bond strengths.
Infrared-ultraviolet double resonance spectroscopy has been applied to study the infrared spectra of the supersonically cooled gas phase complexes of formic acid, acetic acid, propionic acid, formamide, and water with 9-hydroxy-9-fluorenecarboxylic acid (9HFCA), an analog of glycolic acid. In these complexes each binding partner to 9HFCA can function as both proton donor and acceptor. Relative ...
متن کاملIntramolecular Charge-Assisted Hydrogen Bond Strength in Pseudochair Carboxyphosphate
Carboxyphosphate, a suspected intermediate in ATP-dependent carboxylases, has not been isolated nor observed directly by experiment. Consequently, little is known concerning its structure, stability, and ionization state. Recently, carboxyphosphate as either a monoanion or dianion has been shown computationally to adopt a novel pseudochair conformation featuring an intramolecular charge-assiste...
متن کاملIntramolecular hydrogen bond in biologically active o-carbonyl hydroquinones.
Intramolecular hydrogen bonds (IHBs) play a central role in the molecular structure, chemical reactivity and interactions of biologically active molecules. Here, we study the IHBs of seven related o-carbonyl hydroquinones and one structurally-related aromatic lactone, some of which have shown anticancer and antioxidant activity. Experimental NMR data were correlated with theoretical calculation...

متن کاملVerification of a designed intramolecular hydrogen bond in a drug scaffold by nuclear magnetic resonance spectroscopy.
2D 1H-15N HMBC NMR acquired at natural abundance and DMSO titration monitored by 1D 1H NMR verified the existence of an intramolecular hydrogen bond that was designed to mimic the pyrimidinone ring of a class of kinase inhibitors. A scalar coupling across the hydrogen bond was detected in organic and aqueous solvent, suggesting a simple and general approach for testing the propensity of intramo...
