However, a certain region may contain a group of unresolved MRI is an application of NMR (nuclear magnetic resonance), an analytical tool of chemists found in laboratories worldwide. Together, NMR and MRI revolutionized the practice of chemistry and medicine by providing fast, non-destructive, and non-invasive means for the observation of matter from the atomic to the macroscopic scale. Foundations for 2D NMR • All 2D experiments have a direct (t 2) and indirect (t 1) dimension, given by the Varian parameters at and d2. • Digital resolution of a spectrum = # hertz/data point = sw/np for f2 and sw1/ni for f1 in any 2D experiment. • As in a 1D experiment, the digital resolution in the indirect Search the world's information, including webpages, images, videos and more.

1. Introduction. The enormous advances in solution biomolecular NMR over the last approximately 30 years hinged on six separate developments: uniform isotope labeling (13 C and/or 15 N with or without 2 H) that enabled the extension from 2D 1 H– 1 H NMR to heteronuclear multidimensional (3D and 4D) NMR, thereby overcoming spectral degeneracy and chemical shift overlap, and largely solving
