a Structure of strychnine (1). b Quality factors of 1H RCSAs derived from stretched PMMA gel of strychnine: the QCSA factors (red bar) for the two closest configurations RSSRRS and RSRRRS are 0.257 ± 0.006 and 0.275 ± 0.006, respectively. The Q factors are reported with the blue bars. The two configurations RSSRRS and RSRRRS were also the two with the lowest Q factors in the 13C RCSA analysis21. The error bars are standard deviations.
