Bruker 600 MHz NMR

Nuclear magnetic resonance is a physical phenomenon exhibited by atomic nuclei having odd numbers of protons or neutrons (such 1H; 13C; 15N; 19F and 31P). These nuclei possess an intrinsic magnetic moment and angular momentum, enabling them to absorb or emit electromagnetic (EM) radiation when placed in a high-strength magnetic field.

Bruker 600 MHz NMR relies on a powerful 14.1 Tesla superconducting magnet that creates a strong, stable magnetic field to polarize nuclear spins. Radiofrequency (RF) pulses are transmitted via high-performance console electronics and specialized probeheads to excite the nuclei, which subsequently emit detectable EM signals as they relax. The resonant frequency is directly proportional to the external magnetic field strength and subtly modulated by the local electronic environment. Chemists use these micro-frequency variations (chemical shifts and couplings) to elucidate complex molecular and biomolecular structures.
