A sample of 0.6 mL of thesolvent, containing 1 µL of TMS,1was first run on itsown. From this spectrum we determined the chemicalshifts of the solvent residual peak2and the water peak.It should be noted that the latter is quite temperature-dependent (vide infra). Also, any potential ...

The solvent chemical shifts3 were obtained from the spectra containing the solutes, and the ranges of chemical shifts (2) I.e., the signal of the proton for the isotopomer with one less deuterium than the perdeuterated material, e.g., CHCl3 in CDCl3 or C6D5H in C6D6. Except for ...

(iii) solvent effects, (iv) susceptibility measurements/ corrections, and (v) conventions for shielding tensors. These matters will now be taken up by a Task Group including R. K. Harris (chairman), E. D. Becker, S. M. Cabral de Menezes, P. Granger, and K. W. Zilm. An evening ...
The origin of the temperature dependence, the isotope shifts, the shifts with density and solvent, and the hydrogen-bonding shifts is also shown in this chapter. At present, only small fragments of networks have been treated quantum-mechanically, such as the [SiO4]-4 unit to represent ...
