Hi George,
I have opted for ‘Use Lastscale for Calibration’ when in the
integration mode (right click). You have to integrate a relevant spectrum
first and close out of .int mode. Then open a new spectrum, go to .int and
right click for ‘Use Lastscale for Calibration’. I believe
that does exactly what you’re asking.
Good luck,
Vernon

Subject: [AMMRL] integration between spectra
I have a researcher who wants to compare integration between different spectra
(all taken with same parameters).
My thought was to integrate without normalizing or referencing the integral,
but it seems that integration (at least in Topspin) does not provide the =
absolute value.
I don’t see anything in the AU program collection either.
Is there a way to obtain this information?
Or while we always use relative integrals – is there a reason not to
use the absolute values?
I suppose that the data could be imported to a spreadsheet and then absolute
intensities summed within a region, but there should be a better way?
Thanks!
