Abstract
Methods for the analysis and design of solid state nuclear magnetic resonance (NMR) probes are presented. These techniques have been applied to a 200 MHz (1H Larmor frequency) H1–19F–13C cross polarization magic angle spinning probe. Transmission lines have been used throughout the design enabling the production of a highly power efficient probe (1H-22%, F19-17%, and C13-33%) capable of detecting F19 NMR signals while applying proton decoupling fields of 250 kHz. These techniques have proven very useful in designing the probe discussed within the text but are not confined to such a triple resonant design. In fact the techniques are sufficiently general to be useful to all radio frequency design efforts including deuterium wide-line probes and multiresonant high resolution NMR probes. A series of simple but useful design concepts are presented which are used to predict the efficiencies of the design presented.
