The chemical shifts were read and arepresented in Table 1. Except where indicated, thecoupling constants, and therefore the peak shapes, areessentially solvent‑independent and are presented onlyonce.For D 2 O as a solvent, the accepted reference peak (δ? 0) is the methyl signal of the ...
Solvent-peak-suppressed NMR: Correction of baseline distortions and use of strong-pulse excitation. Journal of Magnetic Resonance (1969) 1983, 54, 46 -- 53.Plateau, P., Dumas, C. and Gueron, M. (1983) Solvent- peak-suppressed NMR: Correction of baseline distor- tions and use of strong...
Results Proton Spectra (Table 1). A sample of 0.6 mL of the solvent, containing 1 ?L of TMS,1 was first run on its own. From this spectrum we determined the chemical shifts of the solvent residual peak2 and the water peak. It should be noted that the latter is quite temperature(1)...
