Hi Muhammad,
This is to issue 2. The intensities of a standard five lines (4 protons) should
be 1:4:6:4:1, which obviously is not the case. The heptate intensities should
be 1:6:15:20:15:6:1. There are very weak lines barely seen at the
sides of "pentate". Just double (or triple) the number of scans, I am sure,
you will see all lines.
Good luck!

Hello Muhammad, From the email thread, it looks like Issue 2 has been resolved.
You just need to tease the signal of the smallest peaks out of the noise, either
by recollecting the data with better S/N or perhaps by some processing tricks.
Hello Muhammad,
From the email thread, it looks like Issue 2 has been resolved. You just need

Regarding Issue 1:
You did not give any details about TopSpin version or operating system, but
I think I may have an idea why you need to keep running ATMM. You say that
you run ATMM and "save" the values. But do you know for sure that the file
containing the tune/match settings for 29Si have indeed been saved? I don't
remember where those files get stored, but maybe when it tries to save those
settings, you don't have permission to create and save a new file in
that folder. All other existing nuclei work fine because they already exist.
Does that make sense?
Bob.
