[Question from NMRWiki Q&A forum] optimising o1 in solid stat nmr
optimising o1 in solid stat nmr
I'm a little bit confused about setting o1, in the case of a solid sample First o1 is the offset of the transmitter frequency so sfo1 = BF1 + o1In my case I have to set Sfo1 = BF1 so I must set o1 = 0 HzSecond there is another way to optimize o1 whish is by applying gs and looking the fid, adjusting o1 until we have a good exponential decrease of the fid. In this case o1 value may not be 0 Hz.Does the second technique is valid in solid stat experiences?And which one I have to use?

Proc Natl Acad Sci U S A. 2005 Mar 1;102(9):3284-9
Authors: Havlin RH, Tycko R
We demonstrate an experimental approach to structural studies of unfolded and partially folded proteins in which conformational distributions are probed at a site-specific level by 2D solid-state 13C NMR spectroscopy of glassy frozen solutions. Experiments on chemical...

[NMR900 blog] Opportunities for studying polymorphs and cement-based materials via Ca-43 solid-stat
Opportunities for studying polymorphs and cement-based materials via Ca-43 solid-state NMR
June 11, 2010, University of Ottawa
Calcium is an important component in diverse materials and biochemicals. However, NMR spectroscopy of the only spin-active calcium isotope, Ca-43, is notoriously challenging due to its low natural abundance (0.14 %), low resonance frequency, and quadrupolar nature. Recently, researchers from the University of Ottawa, the NRC Steacie Institute for Molecular Sciences (SIMS-NRC), and Dalhousie University have independently reported advances in studies of inorganic...
