Study of Aqueous Solution of Sodiumdodecylsulfate and Polyethyleneoxide 10000 by NMR NOESY
نویسندگان
چکیده
Two-dimensional Nuclear Overhauser Enhancement SpectroscopY NMR has been applied to study sodiumdodecylsulfate (SDS)/polyethyleneoxide (PEO)/D2O at 10, 20, 25, and 40 ◦C. The results indicate that PEO interacts preferentially with the surface of the micelle aggregates at 20 and 25 ◦C, displacing some water molecules from the hydration sphere. At 40 ◦C the polymer tends to penetrate the interior of the SDS micelle, since its solubility in hydrophobic media increases with temperature.

NMR and fluorometric characterization of mithramycin in aqueous solution.
The assignments for the resonances in the 1H and 13C NMR spectra of mithramycin in aqueous solution have been determined by a combination of 2D NMR methods. Specific NOESY contacts observed between different moieties indicate that the drug assumes a compact conformation in aqueous solution. Fluorescence measurements are consistent with a compact structure for mithramycin in water and confirm th...

The ion-pair association constant values, related to the reaction + were determined by means of the NMR spectroscopy. The values of the thermodynamic functions of the ion pairing process were calculated on the basis of the NMR results. In addition, the association entropy was found to be dependent on the temperature. Comparing the experimental data and the Fuoss theory it is found that ion-pa...
متن کاملResidual water suppression by indirect covariance NMR.
Residual water solvent signals in 2D NMR experiments adversely affect appearance and subsequent analysis of spectra. A method for water suppression that is based on indirect covariance processing is described. It produces a symmetric spectrum with a water signal that is substantially decreased or completely absent. The method, which can be combined with other water suppression schemes, is demon...

NMR spectroscopy is the go-to technique for determining the solution structures of organic, organometallic, and even macromolecular species. However, structure determination of nanoscale aqueous inorganic clusters by NMR spectroscopy remains an unexplored territory. The few hydroxobridged inorganic species well characterized by H Nuclear Magnetic Resonance spectroscopy (H-NMR) do not provide en...

Jingzhaotoxin-I (JZTX-I) purified from the venom of the spider Chilobrachys jingzhao is a novel neurotoxin preferentially inhibiting cardiac sodium channel inactivation by binding to receptor site 3. The structure of this toxin in aqueous solution was investigated using 2-D 1H-NMR techniques. The complete sequence-specific assignments of proton resonance in the 1H-NMR spectra of JZTX-I were obt...
