Hi folks,
I need to do 13C{19F} CPMAS with a 400 Infinity spectrometer and 7.5mmOD
Pencil rotor. I tried to use teflon, Kel-F and vespel spinning tip,
spacer and end tips, but all give large background of either 13C and/or
19F. I was wondering whether anybody out there has any experimence and
suggestions on this kind of experiment.
Thank you very much for your attention.
