# Chemical Shift Ambiguity Index Value Definitions #
# #
# The values other than 1 are used for those atoms with different #
# chemical shifts that cannot be assigned to stereospecific atoms #
# or to specific residues or chains. #
# #
# Index Value Definition #
# #
# 1 Unique (including isolated methyl protons, #
# geminal atoms, and geminal methyl #
# groups with identical chemical shifts) #
# (e.g. ILE HD11, HD12, HD13 protons) #
# 2 Ambiguity of geminal atoms or geminal methyl #
# proton groups (e.g. ASP HB2 and HB3 #
# protons, LEU CD1 and CD2 carbons, or #
# LEU HD11, HD12, HD13 and HD21, HD22, #
# HD23 methyl protons) #
# 3 Aromatic atoms on opposite sides of #
# symmetrical rings (e.g. TYR HE1 and HE2 #
# protons) #
# 4 Intraresidue ambiguities (e.g. LYS HG and #
# HD protons or TRP HZ2 and HZ3 protons) #
# 5 Interresidue ambiguities (LYS 12 vs. LYS 27) #
# 6 Intermolecular ambiguities (e.g. ASP 31 CA #
# in monomer 1 and ASP 31 CA in monomer 2 #
# of an asymmetrical homodimer, duplex #
# DNA assignments, or other assignments #
# that may apply to atoms in one or more #
# molecule in the molecular assembly) #
# 9 Ambiguous, specific ambiguity not defined #
