Field-cycling NMR goes beyond conventional NMR by dynamically varying the magnetic field during the experiment. While standard NMR operates at a fixed field, field-cycling accesses a continuous range of field strengths within a single experiment — revealing relaxation dispersion profiles, molecular dynamics, and field-dependent interactions that are simply invisible at a fixed field. FCNMR's shuttle-based approach preserves full high-field resolution throughout, making it uniquely compatible with existing spectrometer investments.

Illuminated NMR combines light excitation with NMR spectroscopy to probe photochemical and photobiological processes in real time. Photo-CIDNP (Chemically Induced Dynamic Nuclear Polarization) is a key technique: light-activated photosensitizers transfer spin polarization to target nuclei, dramatically enhancing NMR signal sensitivity. This opens a direct window onto radical reaction mechanisms, molecular dynamics, and photoinduced structural changes — at concentrations as low as the nano-molar range.
