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?

[Question from NMRWiki Q&A forum] 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?

A one-year solid-state NMR engineer position available
A one-year engineer position is available in the Magnetic Resonance Laboratory (LRM), INAC/SCIB at CEA Grenoble for the technical maintenance of three BRUKER solid-state NMR spectrometers: two AVANCE 400, one of them coupled to a gyrotron, and one DSX 200. The NMR facility is localized at two different sites and will get very soon a complete system to perform solid-state high-resolution NMR coupled to Dynamic Nuclear Polarization (DNP).
