title: Using magnetic coupling to implement (1)H, (19)F, (13)C experiments in routine high resolution NMR probes.
abstract: We report in this paper the design of (1)H, (19)F, (13)C circuitry using magnetic coupling which can do on demand experiments where one of the three nuclei is observed and the other two are decoupled. The implementation of this circuitry in routine NMR probes is compared with capacitive coupling methods where it was found that by using magnetic coupling the performance of the routine NMR probe was not impacted by the addition of this circuitry. It is surmised that using this type of circuitry would be highly desirable for those chemists doing routine (19)F NMR.
