چکیده
The signal intensity S is given by: S = γB0NB1g(v)/T Where N is the number of nuclei sampled, B1 is the field due to the applied radiofrequency radiation, and g(v) is the lineshape function. Hence, • S ∝ N (large sample and desirability of high isotopic abundance). • S ∝ γ (signals due to nuclei with large γ easiest to observe). • S ∝ B0 (advantage of maximum B0). • S ∝ 1/T (low temperatures give enhanced intensity, in principle).

Inductive Effect of Bioactive Intermolecular Hydrogen Bonding Complex of 1,2,4,5 –Tetrazine and Inorganic Acid by NMR and QTAIM
In this paper, NMR and QTAIM analysis for three substituted of T2SA complex was investigated in the gas and four solvents at DFT level. Intermolecular O–H…N hydrogen bonds between 1,2,4,5-Tetrazine and Sulphurous acids enhance the stability of complex.1,2,4,5-Tetrazine is a highly reactive diene for [4+2] inverse-Diels–Alder cycloaddition processes and an excellent precursor to attain the pyrid...
متن کاملHydration properties and structure of phosphatidylcholine membranes in the presence of n-nonyl bromide.
Interaction of chemical fusogen n-nonyl bromide with a model membrane formed from phosphatidylcholine was studied using 2D-NMR spectra of heavy water and 31P-NMR proton decoupled spectra of the lipid phosphate group in multilamellar lipid dispersions. n-Nonyl bromide was found to influence the hydration layer of the model membrane. No participation of phosphatidylcholine molecules in non-bilaye...
متن کاملNMR relaxation and the structure of a synthetic DNA poly(dA-dT).poly(dA-dT).
1H-1H and 31P-1H nuclear Overhauser effects and 31P NMR spin-lattice relaxation times were measured for a synthetic DNA poly(dA-dT).poly(dA-dT) in a low-salt aqueous solution. The results have shown that all bases in the double helix are anti-orientated with respect to deoxyribose residues and that the sugar-phosphate backbone has an alternating architecture.
متن کامل51V solid-state magic angle spinning NMR spectroscopy and DFT studies of oxovanadium(V) complexes mimicking the active site of vanadium haloperoxidases.
A series of 11 oxovanadium(V) complexes mimicking the active site of vanadium haloperoxidases have been investigated by (51)V magic angle spinning NMR spectroscopy and density functional theory (DFT). The MAS spectra are dominated by the anisotropic quadrupolar and chemical shielding interactions; for these compounds, C(Q) ranges from 3 to 8 MHz, and delta(sigma) is in the range 340-730 ppm. Th...
