(a) 500 MHz 1D 1H-NMR spectrum of 20 mM solution of the (9-cis,11-trans) 18:2 CLA in CDCl3 (T, 298 K; acquisition time, 4.3 s; relaxation delay, 5 s; number of scans, 256; and experimental time, ~25 min). (b–e) Selective 1D TOCSY spectra of the above solution using a mixing time of τm = 33 ms (b), 70 ms (c), 200 ms (d), and 400 ms (e). The asterisk denotes the selected H11 resonance that was excited. For panels (b–e), the magnetization transfer network is illustrated. Adopted, with permission, from []. Copyright 2015, American Chemical Society.
