It would be real helpful to know what the pesky post-doc did
differently between the two spectra, how seperated are the peaks, what
their deacay rates are and the freq. domain s:n. Could this sample have
some extremely broad signals? Assuming this system has the dynamic
range to properly record these signals, I doubt this has anything to do
with a Bruker AC console, Bruker SW or anything else related to a
specific vendor.
We had a case where two peaks with different decay rates (by about a
factor of 3) were almost perfectly overlaped. The amplitude estimate
for these peaks (which we believed to be a single peak) relative to a
third standard peak (which really was a single peak) was a function of
the exponential weighting function we applied before the FT. Of course
it is highly unlikely this is what's going on here.
