New paper: Guide to Simulating Complex NMR Probe Circuits

A new published paper in Concepts in Magnetic Resonance. Significant efforts have been put into probe circuit designs since the inception of Doty Scientific.  Though celebrated for the spinning advancement,  the first circuit on the original MAS probe was also far more efficient and had improved signal to noise -- enabling much shorter acquisition times.  Early probes were all fixed tuned. Doty introduced the first multinuclear MAS probe. In the years since, we have gone from H/X at 100 MHz to quad ...

A Practical Guide to Setting Up Diffusion Measurements

By Paul Ellis As an elder statesman in the area of solid state NMR spectroscopy, it has become obvious that pulsed field gradients (PFG) experiments are and will continue to be important in the future.  Our liquid state colleagues have enjoyed the benefits of PFG for many years.  For example, PFG can remove artifacts within the transverse plane and hence reduce the number scans needed to complete a phase cycle.  Likewise, PFG can be utilized to select coherences in experiments, again ...
