The chemical shielding of TMS was calculated at the pbe1pbe/3-21g* level of theory using the GIAO method. The chemical shielding of TMS was used as the reference (0 ppm) to obtain all other chemical shifts. A series of small organic molecules were optimized and the chemical shieldings were calculated in the same manner as that for TMS. To correct for biases arising from the applied level of theory, especially the bias from the small basis set size, a linear regression analysis was used. The slope and intercept from this regression was used to correct the calculated chemical shifts. The chemical shift was calculated by subtracting the chemical shielding value of the compound of interest from that of TMS and applying the slope and intercept corrections obtained from the regression analysis. corrected_shift=((TMS_shielding - uncorrected_shielding)+1.006)/0.963 13C chemical shifts: Tetramethylsilane (TMS) was geometry optimized at the B3LYP/6-311+g* level of theory. The chemical shielding of TMS was calculated at the pbe1pbe/3-21g* level of theory using the GIAO method.

A series of small organic molecules were optimized and the chemical shieldings were calculated in the same manner as that for TMS. To correct for biases arising from the applied level of theory, especially the bias from the small basis set size, a linear regression analysis of theoretical versus experimental chemical shifts was used. The slope and intercept from this regression was used to correct the calculated chemical shifts. The chemical shift was calculated by subtracting the chemical shielding value of the compound of interest from that of TMS and applying the slope and intercept corrections obtained from the regression analysis. Corrected_shift=((TMS_shielding - uncorrected shielding) -4.53)/0.85 15N chemical shifts: A cyclic pentamer of ammonia (NH3_5) was geometry optimized at the B3LYP/6-311+g* level of theory. The chemical shielding of NH3_5 was calculated at the pbe1pbe/3-21g* level of theory using the GIAO method. The chemical shielding of NH3_5 was used as the reference (0 ppm) to obtain all other chemical shifts. A series of small organic molecules were optimized and the chemical shieldings were calculated in the same manner as that for NH3_5. To correct for biases arising from the applied level of theory, especially the bias from the small basis set size, a linear regression analysis was used. The slope and intercept from this regression was used to correct the calculated chemical shifts. The chemical shift was calculated by subtracting the chemical shielding value of the compound of interest from that of NH3_5 and applying the slope and intercept corrections obtained from the regression analysis. Corrected_shift=((NH_3_5_shielding - uncorrected_shielding)+10.2)/0.9088 31P chemical shifts: Phosphoric acid (H3PO4) was geometry optimized at the B3LYP/6-311+g* level of theory. The chemical shielding of H3PO4 was calculated at the pbe1pbe/3-21g* level of theory using the GIAO method. The chemical shielding of H3PO4 was used as the reference (0 ppm) to obtain all other chemical shifts. No correction for linear bias or offset was applied to calculated 31P chemical shifts. The chemical shift was calculated by subtracting the chemical shielding value of the compound of interest from that of H3PO4. Shift=(H3PO4_shielding - shielding) ; loop_ _Chem_shifts_calc_software.Software_ID _Chem_shifts_calc_software.Software_label _Chem_shifts_calc_software.Entry_ID _Chem_shifts_calc_software.Chem_shifts_calc_type_ID 1 $software_1 bmst000162 1 stop_ save_ ################################# # Theoretical chemical shifts # ################################# save_theoretical_chem_shifts _Theoretical_chem_shift_list.Sf_category theoretical_chem_shifts _Theoretical_chem_shift_list.Sf_framecode theoretical_chem_shifts _Theoretical_chem_shift_list.Entry_ID bmst000162 _Theoretical_chem_shift_list.ID 1 _Theoretical_chem_shift_list.Chem_shifts_calc_type_ID 1 _Theoretical_chem_shift_list.Chem_shifts_calc_type_label $chem_shifts_calc_type _Theoretical_chem_shift_list.Model_atomic_coordinates_ID 1 _Theoretical_chem_shift_list.Model_atomic_coordinates_label $conformer_family_coord_set_1 _Theoretical_chem_shift_list.Fermi_contact_spin_density_units ? _Theoretical_chem_shift_list.Chem_shift_1H_err ? _Theoretical_chem_shift_list.Chem_shift_2H_err ? _Theoretical_chem_shift_list.Chem_shift_13C_err ? _Theoretical_chem_shift_list.Chem_shift_15N_err ? _Theoretical_chem_shift_list.Chem_shift_19F_err ? _Theoretical_chem_shift_list.Chem_shift_31P_err ? _Theoretical_chem_shift_list.Details ? _Theoretical_chem_shift_list.Text_data_format ? _Theoretical_chem_shift_list.Text_data ? loop_ _Theoretical_chem_shift.ID _Theoretical_chem_shift.Entity_assembly_ID _Theoretical_chem_shift.Entity_ID _Theoretical_chem_shift.Comp_index_ID _Theoretical_chem_shift.Comp_ID _Theoretical_chem_shift.Atom_ID _Theoretical_chem_shift.Atom_type _Theoretical_chem_shift.Fermi_contact_spin_density _Theoretical_chem_shift.Val _Theoretical_chem_shift.Val_err _Theoretical_chem_shift.Auth_seq_ID _Theoretical_chem_shift.Auth_comp_ID _Theoretical_chem_shift.Auth_atom_ID _Theoretical_chem_shift.Entry_ID _Theoretical_chem_shift.Theoretical_chem_shift_list_ID 1 1 1 1 1 H1 H ? 9.221 ? 4_aminobenzoic_acid ? ? bmst000162 1 2 1 1 1 1 H2 H ? 9.434 ? 4_aminobenzoic_acid ? ? bmst000162 1 3 1 1 1 1 H3 H ? 7.553 ? 4_aminobenzoic_acid ? ? bmst000162 1 4 1 1 1 1 H4 H ? 7.646 ? 4_aminobenzoic_acid ? ? bmst000162 1 5 1 1 1 1 H5 H ? 3.943 ? 4_aminobenzoic_acid ? ? bmst000162 1 6 1 1 1 1 H6 H ? 3.948 ? 4_aminobenzoic_acid ? ? bmst000162 1 7 1 1 1 1 H7 H ? 6.143 ? 4_aminobenzoic_acid ? ? bmst000162 1 8 1 1 1 1 C8 C ? 139.275 ? 4_aminobenzoic_acid ? ? bmst000162 1 9 1 1 1 1 C9 C ? 140.691 ? 4_aminobenzoic_acid ? ? bmst000162 1 10 1 1 1 1 C10 C ? 117.551 ? 4_aminobenzoic_acid ? ? bmst000162 1 11 1 1 1 1 C11 C ? 118.072 ? 4_aminobenzoic_acid ? ? bmst000162 1 12 1 1 1 1 C12 C ? 124.893 ? 4_aminobenzoic_acid ? ? bmst000162 1 13 1 1 1 1 C13 C ? 156.784 ? 4_aminobenzoic_acid ? ? bmst000162 1 14 1 1 1 1 C14 C ? 177.438 ? 4_aminobenzoic_acid ? ? bmst000162 1 15 1 1 1 1 N15 N ? 79.116 ? 4_aminobenzoic_acid ? ? bmst000162 1 stop_ save_ ##################################### # Conformer family coordinate set # ##################################### save_conformer_family_coord_set_1 _Conformer_family_coord_set.Sf_category conformer_family_coord_set _Conformer_family_coord_set.Sf_framecode conformer_family_coord_set_1 _Conformer_family_coord_set.Entry_ID bmst000162 _Conformer_family_coord_set.ID 1 _Conformer_family_coord_set.Details ? loop_ _Conformer_family_software.Software_ID _Conformer_family_software.Software_label _Conformer_family_software.Entry_ID _Conformer_family_software.Conformer_family_coord_set_ID 1 $software_1 bmst000162 1 stop_ loop_ _Atom_site.Model_ID _Atom_site.ID _Atom_site.Label_entity_assembly_ID _Atom_site.Label_entity_ID _Atom_site.Label_comp_index_ID _Atom_site.Label_comp_ID _Atom_site.Label_atom_ID _Atom_site.Auth_seq_ID _Atom_site.Auth_comp_ID _Atom_site.Auth_atom_ID _Atom_site.Type_symbol _Atom_site.Cartn_x _Atom_site.Cartn_y _Atom_site.Cartn_z _Atom_site.Entry_ID _Atom_site.Conformer_family_coord_set_ID 1 1 1 1 1 1 H1 1 1 H1 H -0.541 -2.122 -0.062 bmst000162 1 1 2 1 1 1 1 H2 1 1 H2 H -0.504 2.165 0.046 bmst000162 1 1 3 1 1 1 1 H3 1 1 H3 H 1.929 -2.157 -0.037 bmst000162 1 1 4 1 1 1 1 H4 1 1 H4 H 1.979 2.151 0.071 bmst000162 1 1 5 1 1 1 1 H5 1 1 H5 H 3.964 -0.876 0.290 bmst000162 1 1 6 1 1 1 1 H6 1 1 H6 H 3.984 0.808 0.330 bmst000162 1 1 7 1 1 1 1 H7 1 1 H7 H -3.720 -0.934 -0.068 bmst000162 1 1 8 1 1 1 1 C8 1 1 C8 C 0.011 -1.189 -0.034 bmst000162 1 1 9 1 1 1 1 C9 1 1 C9 C 0.041 1.226 0.027 bmst000162 1 1 10 1 1 1 1 C10 1 1 C10 C 1.398 -1.208 -0.016 bmst000162 1 1 11 1 1 1 1 C11 1 1 C11 C 1.426 1.215 0.045 bmst000162 1 1 12 1 1 1 1 C12 1 1 C12 C -0.689 0.028 -0.011 bmst000162 1 1 13 1 1 1 1 C13 1 1 C13 C 2.131 -0.005 0.023 bmst000162 1 1 14 1 1 1 1 C14 1 1 C14 C -2.163 0.104 -0.025 bmst000162 1 1 15 1 1 1 1 N15 1 1 N15 N 3.517 -0.021 -0.012 bmst000162 1 1 16 1 1 1 1 O16 1 1 O16 O -2.817 1.130 -0.005 bmst000162 1 1 17 1 1 1 1 O17 1 1 O17 O -2.763 -1.120 -0.062 bmst000162 1 stop_ save_
