NMR Spectroscopy

NMR Spectroscopy

NMR Spectroscopy. CHEM 430. Proton-Proton Correlation Through J-Coupling. 2D NMR Basics. In actuality, the techniques we have already covered 1 H, 13 C, and DEPT are 2-D (frequency vs. intensity) however, by tradition the intensity component is dropped when discussing dimensionality
