What is Field-Cycling NMR?

Field-cycling NMR (Nuclear Magnetic Resonance) is a technique that involves changing the magnetic field strength during an NMR experiment. In traditional NMR, a constant magnetic field is applied to the sample, causing the nuclei in the sample to resonate at a specific frequency. By detecting the resonance frequency, we can learn about the sample's chemical and physical properties. In field-cycling NMR, the magnetic field is periodically varied over a range of strengths, causing the sample's resonant frequency to change as well. This allows for the observation of additional information about the sample, including its relaxation properties and interactions with the surrounding environment.

Perform Field-Cycling NMR requires special instruments

We designed the High-Field Field-Cycler to integrate with commercial high-field NMR spectrometers, providing researchers with a highly advanced method for measuring relaxation properties. This instrument delivers exceptional sensitivity and high-resolution spectra, and is capable of conducting diverse field-cycling studies. It has become a vital tool in molecular science, allowing researchers to explore molecular interactions and folding mechanisms through photo-CIDNP. The instrument's capabilities are further enhanced by the inclusion of a correlated illumination device.
