Hello,
If you want to split an existing project into two then probably the best option is to duplicate the existing project and then delete spectra from each of the two projects. (Back everything up first of course!)
One of the problems with doing this kind of thing is that your resonances will not be linked between the two projects, so the shift values (calculated from peaks in the project) will drift apart, and also you will have to duplicate the assignment of resonances.
Re-merging the two would likely also be non-trivial, should you ever want to do that in future.
If you want to reduce memory usage, but still need to view the spectra, then you could try pre-calculated contours, at least if you are done with peak picking and don't mind seeing only a fixed set of contour levels. This functionality can be reached via the Experiment --> Spectra dialog in the Display Options tab. Click on a spectrum and click on Contour Files.
