New Apparatus for Double Nuclear Magnetic Resonance Experiments

Nuclear Magnetic Resonance (NMR) spectroscopy is a widely used technique in chemistry that gives an insight into structure of molecules, properties of materials, and dynamics of molecular systems. Many attempts to do solid state spectroscopy have been thwarted by the spectrum broadening that occurs because the molecules are close together, tightly bound, and thus interact easily. We wish to show that using a combination of dynamic nuclear polarization and cross polarization of nuclei can result in successful static solid-state experiments. We believe that this can be accomplished by a chain of spin polarization from electron, to proton, to finally, carbon thirteen. Though we do not have data yet, similar experiments involving transfer of spin have shown a significant improvement in detected signal. Additionally, we have a unique probe design that will allow us to do a variety of experiments on many different nuclei.
