I seem to have a problem here and hope there is help out there. I have had
a request to run several 1D Sn-119 experiments here. I am in the process
of setting the instrument up. I am able to detect TMSn 60% no problem with
a 600 ppm window. The problem is that the signal is split (7 peaks), even
with the decoupler on. Is this suppose to be that way or is my decoupler
settings off. Am I seeing long range spliting from the protons? The
resonances I am looking at come at ca. -650 ppm (TMSn). Can I open my
spectral window more without everything getting wacky. I will freely
accept any advice or recommendations.

If someone already has a paramenter set for a QE-300 they could send me
that would help out a lot.

Thank You
