New Doty ENC Suite at Asilomar: Surf And Sand
ENC News: Our new suite, Surf and Sand. We will be open Sunday through Wednesday evenings from 7:00 to 11:00 PM. Come by for ice cream, information, and pleasant conversation.
A Practical Guide to Diffusion Measurements – Expanded
Earlier this year, we introduced a white paper, A Practical Guide to Setting Up Diffusion Measurements Utilizing Pulsed Field Gradients. We are re-introducing the paper with additional material to include solids diffusion methods. The paper is now presented in three parts. Part one is the original material - with part 2 and 3 being new material. A Practical Guide to Setting Up Diffusion Measurements Utilizing Pulsed Field Gradients. Daniel Arcos, John Staab, Bibhuti Das, Paul D Ellis, and F. David Doty Part ...
To Deuterate Your Proteins – or Not to Deuterate? That is the Question.
MAS has long been an integral technique in Solid State NMR, beginning with investigations on typically inorganic samples, but quickly moving to biological samples with ever increasing molecular weight. The resulting complexity of the NMR spectrum has lead to the use of High-resolution inverse 1H detection in Solid State NMR spectroscopy for large molecules. New developments in protein biochemistry and fast spinning have contributed to this rapidly evolving area of NMR. Bibhuti Das, Paul Ellis and F. David Doty present ...
Introducing: Doty WB Ultra-Range NMR MAS Probe
At the Rocky Mountain Conference in Snowbird Utah, USA we introduced a new wide bore MAS probe we call the “WB Ultra Range”. It features a broad temperature range, a broad tuning range, and a broad range of spinner options. The Doty WB Ultra-Range MAS Probe Broad Temperature Range -170 oC to +270 oC (and ultimately higher) Fully Multinuclear 31P to 103Rh Broad Tuning Range with Most Tuning Inserts Double-Tuned 1H/X or Triple-Tuned 1H/X/Y Broad Range of Spinner Options 7 mm, 5 mm, ...

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 ...
Access Sample Temperatures to 250 ºC in a Narrow Bore Wideline Probe!
To illustrate the capability of a novel 3 mm H/X wideline narrow bore probe with extended VT range, we performed a variable temperature experiment on Pb(NO3)2 over the temperature range from -110 °C to +250 °C. Those data are summarized in figure below. The first thing that is apparent is the isotropic chemical shift is changing as a function of temperature. These data match the well-known temperature dependence reported by Bielecki and Burum (JMR 1995). Secondly, comparing the powder lineshape ...

Total Eclipse at Doty Scientific 8-21-2017
Solar Photos by Rochelle Doty at Doty Scientific. (Note the moon outline in photo 2.) Solar Photos by Vince Cothran at Doty Scientific. The day was perfect... but the 93 degree weather made canopies a must, and a large fan helped too. We want to thank Vince Cothran for the fine solar projector he made. It was a real ...
