14. This analysis cannot be easily performed with the line shift because the large NMR linewidth at low temperatures results in large error bars for the relatively small NMR line shift.
15. For the considered site configurations, the external values of the dipolar magnetic fields are 1630 and -770 Oe, respectively.
