Fan,
The way to deal with this situation is, rather than deassigning
the resonance(s), simply deassign the peaks in the spectra from the form
where you made the mistake. Remember that in analysis, the resonances
act as intermediates between observed NMR signals and atom assignments.
You can break the relationship either between peaks and a resonance, or
between the resonance and the atom assignment allowing you to deal
flexibly with exactly the sort of situation you describe.
In practice, in this case you would do something like pop up the
shift list for the form you want to deassign, find the resonance(s) and
"show shift list peaks" then you can remove the resonance assignments from
those peaks (and add some new resonance and spin system information)
leaving the peaks/resonance/atom assignment for the other shift list
untouched.
