High-Field NMR Facility

High-Field NMR Facility at NINT

Introduction

NMR spectroscopy can provide a wealth of information about the nature of solute molecules and solute-solvent interactions. NMR has been widely used in a variety of areas:

  • Determine Solution Structure of Small Molecules
  • DNA and Protein Structure Determination
  • Molecular Dynamics
  • Diffusion Measurements
  • Hydrogen Bonding Determination/pKa Measurements
  • Drug Screening
  • Metabolite Analysis -Metabolomics
  • Natural Product Chemistry
  • Polymer Chemistry
  • Environmental Chemistry

The space

Located at the second floor of NINT building, the NINT High-Field NMR facility consisting of a VNMRS 600 MHz spectrometer provides access to state-of-the-art NMR instrumentation.
