Detailed description of the fields

### _Ambiguous_atom_chem_shift.Ambiguous_shift_set_ID (AmbiguousShiftSetID)

(go to parent tag category listing)

NMR-STAR tag name | _Ambiguous_atom_chem_shift.Ambiguous_shift_set_ID

Description

NMR-STAR name: _Ambiguous_atom_chem_shift.Ambiguous_shift_set_ID
An integer value that defines a set of chemical shifts that form a mutually ambiguous group. For ambiguity codes of 4 or 5, various combinations of assigned chemical shifts may form sets where the chemical shift assignments are not specifically known, but it is known that the chemical shifts belong to one atom in the set.
