NMR module

Function and Applications

The NMR module is used with the ESR/NMR control unit to study nuclear magnetic resonance in glycerin, polystyrene, and Teflon. The equipment set consists of the factory-adjusted base unit with two magnetic coils, the NMR probe, the glycerin sample, the polystyrene sample, the Teflon sample, and an empty reference sample. A measurement report is supplied with each NMR module. This report specifies the resonance frequency for glycerin and the strength of the permanent magnetic field of the respective module.

The observation of resonances is achieved through high-frequency induced transitions when varying the external magnetic field. The resonance absorption curves can be displayed using a simple dual-channel oscilloscope.

Benefits

• Easy handling thanks to compact design.
• Versatile basic unit.
