Anyway, while working on this experiment, I noticed a problem: When the
FID is being collected (NS=8), on about the third pulse, the data cancels
out a large portion of the FID's intensity and shape. I'm not sure what
causes it but my first impression is that the inversion/recovery pulse
sequence is not timed correctly, resulting in a phase difference and the
cancellation.
Does anyone have an idea what is up? I've tried several samples, with and
with-out ferrocene and get the same result. Also, my T1 plots do not look
to great, with a huge variance in their result.
I should note that while I have become pretty good at collecting simple
spectra and managing file systems, my quantum is pretty rusty, especially
when it comes to pulse sequences.
Thanks in advance,
Armando the <partially> great.
