This popup window shows the locations and identities of all of the peak
dimensions to which a particular resonance is assigned, together with
the averaged chemical shift values for the resonances derived from
these assigned locations
The upper table lists the positions in the spectra that the resonance is
assigned to. Thus, the user may see the complement of peaks that the resonance
contributes to and what the chemical shift positions of these peaks are, in the
relevant assigned dimension. This display is handy for identifying chemical
shift outliers that may be indicative of a mistaken assignment.
The lower table shows the averaged chemical shift values that derive from the
resonance’s assignment to the various peak dimensions. It should be noted that
each peak dimension does not necessarily contribute equally to the shift
average. The average is weighted by spectrum (and hence peak) dimension. By
default this is even, but imprecise or ambiguous peak dimensions are often
down-weighted and precise ones are up-weighted. The spectrum dimension
weightings are set via the “Tolerances” tab, “Shift Weighting” column of main
Spectra option.

| Table 1 |
| Peak List |
The peak list of the peak to which the current resonance is assigned (experiment:spectrum:list number) |
| Peak |
The serial number of the peak, within its peak list, to which the current resonance is assigned |
| Dim |
The dimension number of the peak that the resonance is assigned to |
| Position |
The position of the peak dimension, typically in ppm units |
| Assignment |
The assignment annotation of the whole peak |
| Shift List |
The shift list name and number that the peak uses (via its experiment record) |
Chemical Shifts
