1 H NMR chemical shift, line width, indirect nuclear splitting value, peak area integration value, and spin鈥搇attice and spin鈥搒pin relaxation times at 298K are compared for low-concentration isotropic solutions of n -octylammonium n -octadecanoate prepared via different techniques and conditions...
The complex CHCl3@7 was dissolved in tetrachloroethane-d2 in a concentration of about 1 mM. The NMR samples were heated up to a defined temperature and allowed to equilibrate. According to the 1H NMR spectra, equilibrium was reached after 2–4 h. The 1H NMR spectra for determination of ...
The molecular reorientation in liquid chloroform and chloroform‐dhas been studied as a function of temperature and pressure by analysis of the Raman line shapes for the ν1(A1) C–H and C–D stretching modes at 3020 and 2256 cm1, respectively. The measurements cover the temperature range 303...
The activation energy, E a( D ⊥), determined from the ν 3 bandshape measurements was 30% higher than the average value from the NMR and dielectric studies. The deviation is believed to result from the sensitivity of this quantity to the fractional Lorentzian character of the fitting ...
halobium (residues 1-36) solubilized in a mixture of methanol-chloroform (1:1), 0.1 M LiClO4 organic mixture, or in perdeuterated sodium dodecyl sulfate (SDS) micelles, were determined by 2D 1H-NMR techniques. 324 and 400 NOESY cross-peak volumes were measured in NOESY spectra of sA in ...
However, if proteins and lipids are not sufficiently removed from the sample before one-dimensional (1-D) proton-nuclear magnetic resonance (1H-NMR) spectroscopy, the resulting spectrum cannot be reliably quantified. This is because broad, low intensity peaks produced by macromolecules disrupt the ...
