Studying Complex Structures in the Blink of an Eye

The first solid-state nuclear magnetic resonance (SSNMR) spectroscopy measurements under magic angle spinning at an unprecedented 100,000 rotations per second have been reported.  SSNMR is a researcher’s equivalent to MRI imaging in medicine.  For solid materials, the faster the sample spins the narrower the lines in the data which enables new insights in materials.  Ultrafast spinning occurs at frequencies of 100 kilohertz (or faster), meaning in the time it takes you to blink it will have spun 35,000 times.  Researchers used this technology to study the coordination chemistry of corroles, which have potential applications as catalysts.  Certain molecular interactions with corroles have proven elusive and this method provides new insight.  Findings were triangulated with theoretical calculations and correlation experiments to provide decisive information.  This powerful tool can be used to study the structures and interactions in increasingly complex structures.
