optimising o1 in solid state nmr

optimising o1 in solid state 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?

[Question from NMRWiki Q&A forum] about sideband in solid-state NMR about sideband in solid-state NMR Hi, dear all, I've encounter a strange phenomemon.While the target speed of MAS was set to be 12kHz, the sidebands of 6kHz difference with respect to the center peak arised.What may cause the problem? Is there any possibility that the real speed is half of the displayed speed?

J Biomol NMR. 2004 Nov;30(3):283-6 Authors: Howe PW Maximising solubility is a key step in applying solution-state NMR to proteins. The 'microbatch' crystallisation screening method can be adapted to screen for protein solubility. In this approach, drops of test solutions are placed under paraffin oil in 96-well screening plates. This requires very small amounts of protein, is easy to set up...	nmrlearner	Journal club	0	11-24-2010 10:03 PM
