Intermolecular hydrogen bonding competes with an intramolecular hydrogen bond when methanol binds to an α-hydroxyester. Disruption of the intramolecular OHÁÁÁOQC contact in favour of a cooperative OHÁÁÁOHÁÁÁOQC sequence is evidenced by FTIR spectroscopy for the addition of methanol to the esters methyl.

Sep 27, 2004. yet. Isotope-editing/filtering techniques can tell us whether a. NOESY cross-peak is intra- or intermolecular. Therefore, discrimination of the two kinds of hydrogen bonds may be possible if information such as the proton pairs closest to the hydrogen bond are gathered. This is, however, an indirect method.

Jan 19, 2012. Intermolecular hydrogen bonding (HB) is an interaction governing self-assembly and is responsible for the architecture and organization of molecular aggregates [ 1], and also ligand–receptor interactions that are responsible for the bioactivity of compounds [2]. Moreover, intramolecular HB has been found.

The vibrational analysis (FT-IR and FT-Raman) for the new 1-(2-chlorobenzoyl) thiourea species suggests that strong intramolecular interactions affect the conformational properties. The X-ray structure determination corroborates that an intramolecular N-H⋯OC hydrogen bond occurs between the carbonyl (-CO) and.

Abstract: 2-Methoxyphenol (2MP) solutes form weak complexes with toluene solvent molecules. The complexes are unusual in that the 2MP hydroxyl has an intramolecular hydrogen bond and simultaneously forms an intermolecular hydrogen bond with toluene and other aromatic solvents. In the equilibrated solute- solvent.

The measured frequency of the intramolecular H bond in the current study provides a more subtle probe of the donor and acceptor influence of the intermolecular H bonds. The subtle interactions of multiple intrarmolecular and intermolecular hydrogen bonds are revealed which may be useful in the characterization of gas.
