✦ Synopsis

Abstract

The NMR linewidth of the formyl proton in dimethylformamide has been studied in the neat liquid and twelve organic solvents. It varies by more than one order of magnitude which is referred to solvent viscosity changes and to the protonation of dimethylformamide. The data do not allow the distinction between N‐ and O‐protonation without further knowledge of the solvent dependence of either the nitrogen‐14 spin lattice relaxation time or the spin‐spin coupling ^2^J(NH).

## Abstract The proton chemical shift values for the methyl groups in the nine monomethylquinolizidines are determined in deuterochloroform and benzene solutions. This solvent change results in the shielding of all the methyl groups except those in 1(a)‐and 3(a)‐methylquinolizidine which become des

## Abstract It is shown that the effect of pH changes can be measured in proton NMR spectra through the pH sensitivity of the signal intensities of metabolite protons exchanging with water. To observe this phenomenon, pulse sequences must be used that can sensitively observe these exchangeable prot
