Webb17 sep. 2024 · NMR lineshape analysis and exchange spectroscopy (EXSY) are used to quantify the proton exchange rate. The obtained exchange rate is then used to explain the diffusion behaviour of the exchangeable proton as measured by pulse field gradient NMR methods; a marginal anomaly in the translational dynamics of the exchangeable proton … WebbProton NMR and Piezoelectricity in Tetramethylammonium Chloride J.

WebbWhen an NMR spectrum is taken of the molecule below, there is the expected 5H in the aromatic region, triplet (3H) and quartet (2H) upfield of the aromatic region. After adding a drop of acidic D2O, the spectrum changes to one that just has 5H aromatic protons and an upfield 3H singlet.
