Basic NMR Concepts - Boston University

Introduction Nuclear Magnetic Resonance (NMR) is a powerful relatively non-selective analytical tool, which enables you to ascertain molecular structure including relative configuration, relative and absolute concentrations, and even intermolecular interactions. Once challenging and specialized NMR techniques have become routine. NMR is indeed
