The effect of pressure and temperature of self-diffusion coefficients in several concentrated deuterium oxide diamagnetic electrolyte solutions

AbstractThe pressure dependences of the self-diffusion coefficients of deuterium oxide in 4.5m solutions of LiCl–D2O and CsCl–D2O (also 7m) and 3.06m CaCl2–D2O have been measured by the NMR spin-echo method at 30°C, 60°C, and 90°C.

Spectroscopic studies of ionic solvation. XXI. A raman, infrared, and NMR study of sodium perchlorate solutions in nonaqueous solvents

AbstractSodium perchlorate solutions in several nonaqueous solvents were examined by23Na,35Cl-NMR, infrared, and Raman spectroscopic techniques. The formation of contact ion pairs lowers the symmetry of ClO4– ion from Td to C3v or C2v provided that the interaction is fairly strong.

Diastereotope Methylenprotonen und Methylgruppen in 2-Substituierten 1,6-Methano [10] Annulenen

The double magnetic non equivalence of the diastereotopic methylene protons resp. geminal methyl groups of 2-substituted 1,6-methano [10]annulenes were observed in five solvents. It was found that ??AB for one of the two methylene groups were much smaller than ??A 'B' for the other and that ??

N.M.R. Spectral Studies of Some Quinolone Derivatives. Part II.1 Further Studies of the Effect of Substitution on the Degree of Hydrogen Bonding

The chemical shift of the NH proton for a series of 4-quinolone derivatives has been studied. It is proposed that the inhibition of ?-hydrogen bonding is a dominant factor which contributes to the observed NH chemical shift. Details of the 1H n.m.r.

The Use of Protonation Induced Changes in Carbon-13 NMR Chemical Shifts to Investigate the Solution Microscopic Structure of Partially Protonated Polybasic Molecules

Changes in the NMR chemical shift of carbon-13 nuclei upon protonation of a nearby basic center are shown to be a useful method of probing the microscopic site of protonation of molecules containing multiple basic centers, such as diethylenetriaminepenta-acetic acid (DTPA).
