Current Research

The nuclear magnetic resonance (NMR) frequencies of atoms such as 1H, 13C, 31P, and so on, are exquisitely sensitive to their environment. That environment includes electrons in closed shells, open shells and bonds, and other nuclei in constant motion, and also depends on the orientation of these objects relative to the large magnetic field we apply to the sample. We use the NMR frequency to probe the structure of materials.

However, to understand these NMR frequencies we must also be able to interpret them. An ever-more-important aspect of our research is therefore to use high-level quantum chemical methods to calculate molecular structures, and all sorts of spectra. We do these ‘computer experiments’ on everything from diatomic molecules, to endohedral fullerenes (atoms or molecules trapped in buckyball cages), to crystalline metal oxides. This work impacts areas from fundamental chemistry, to catalysis, environmental remediation, and even quantum computing.
