2D NMR Techniques

2D NMR techniques are advanced methods used to analyze the structure of molecules by examining interactions between atomic nuclei. Unlike traditional 1D NMR, which provides a single spectrum, 2D NMR creates a two-dimensional map showing how different atoms in a molecule are connected or close to each other. This helps chemists determine the arrangement of atoms, identify complex molecules, and understand their structure more clearly. Techniques like COSY, HSQC, and NOESY are common examples, each revealing different types of atomic relationships, aiding in precise molecular characterization.
