(A), (B) and (C) refer to the labeling of the molecules in Fig. 6(c)
Intramolecular distances (within molecule A) are shown in bold
The closest distances to the next nearest eight 1H nuclei external to the central H7 and H8 nuclei are underlined
Only intramolecular H7-H8 polarization transfer was considered in the simulations, i.e., initial density matrix corresponds to Iz for H7a and H7b, with the read out only on H8 of molecule A. See the representative SPINEVOLUTION input files in the Appendix.
