Hello,
I am not sure that the subject heading exactly captures what I would like to
do, so here is a more detailed description: Would it be possible in Analysis
to measure (i.e. display) the chemical shift difference between two arbitrary
points in one spectrum? What I mean by this is the ability to 'mark' or
indicate two points in the spectrum and have the program display the exact
differences in both (or more) axes? Preferably in both (k)Hz and ppm?
For solid state NMR applications this could be particularly interesting for
picking out side bands appearing in the spectra, or compare the chemical
shift difference between two peaks with the MAS rate (to determine possible
R2 conditions, for instance). For such purposes, units of kHz would be most
practical.
By the way, it might actually be nice to (at some point) have some
capabilities to mark (or 'assign') particular spinning side bands within
SSNMR spectra. Currently those remain usually unmarked and could cause some
confusion with 'real' peaks. Especially folded or aliased side bands can be
tricky to identify.
