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. However, 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.

High resolution Field Cycling NMR

The Field-Cycling NMR technique is a technique that changes the magnetic fields of the sample during the experiment. This method can perform applications that require measurements at different magnetic fields, for instance, MRI contrast agent studies, protein dynamics, or material science.

In-situ illumination technologies for NMR

In situ illumination of liquid-state NMR samples opens a field for studies of light-dependent chemical or biological interactions. Among those studies, the light-driven reactions between amino acid and dye molecule, studied by photochemical induced nuclear polarization (photo-CIDNP) in solution, have been investigated to show characteristic changes in spin polarization upon various magnetic fields. The applications of photo-CIDNP, such as detecting aromatic amino acids or proteins in solution in the low micro-molar to nano-molar concentration range, are getting compelling simultaneously.
