Hi All,
We are trying to implement a silicon-HMBC experiment and are having trouble
getting the Si-axis to be in the range we want.
The sweep width we were going for was 200 ppm centered at -40 ppm, but the
spectra we keep getting are labeled as ranging from 960,777 to around 960,384 ppm
(SW~400 ppm). Does anyone have any ideas why this is happening and how to fix it?
I feel like I am missing something simple but am at a loss.
For reference, the spectrum below is of tetraethoxy silane (~-81.8 ppm).
Thanks!
Best,
Tedd
