• Resumen

  • Increasingly, the undergraduate chemistry curriculum includes nuclear magnetic resonance (NMR) spectroscopy. Advanced NMR techniques are often taught including two-dimensional gradient-based experiments. An investigation of intermolecular forces including viscosity, by a variety of methods, is often integrated in the undergraduate physical and organic laboratory curricula. An experiment is described that couples advanced NMR techniques with the investigation of viscosity, a physical property based on molecular structure.
