All 2D NMR experiments were recorded with 512 (t1) 2048 (t2) complex data points. 128 scans were acquired over a spectra width of 5000 Hz in both dimensions for samples in D 2 O and 8000 Hz for H 2 O/D 2 O (90:10) samples.

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. 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 Advanced prediction, processing, and interpretation software for nuclear magnetic resonance spectroscopy.

Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful technique for the analysis of molecular structure and function. Its familar application in the public domain, Magnetic Resonance Imaging (MRI), is widely used in macroscopic tissue and organ imaging for disease diagnosis or functional studies. Everything students need to know about 1D, 2D-NMR, solid state and dynamic NMR spectroscopy as well as NMR imaging is presented in this text, illustrated by examples and applications from organic, macromolecular, polymer and biochemistry. This edition features problems and solutions for the reader to check their understanding. 2. Standard 13C NMR 2.1 What is it?
