FT-NMR (a) and PI-SSFP (b, c) sets were collected in 40 s; traces in blue show zoom-ins to the 10–60 ppm regions. Listed for each trace are main experimental acquisition conditions; the PI-SSFP data involved M = 12 phase shifts with a TR = 30 ms. Indicated are the full-widths at half-height (FWHH) of representative peaks. Red arrows highlight quaternary carbons C1 and C12 at 141 and 36.5 ppm, possessing longer T1s that negatively bias sensitivity in conventional FT-NMR but not in the new PI-SSFP experiment. All remaining visible peaks have T1s ≤ 1s. The cropped solvent peak is indicated by an asterisk.
