Fig. 2. (a) 2D 1H–1H hyperpolarised UF TOCSY spectrum obtained in a single scan on the sample described in (Fig. 1d). (b) Conventional 2D 1H–1H TOCSY spectrum measured on the same sample after rethermalisation and shimming, in 4 hours and 25 minutes using 128 t1 increments with 8 scans per increment. The data for obtaining the conventional spectra were processed with same acquisition (t2) and evolution (t1) times as used for its corresponding 2D hyperpolarized UF spectra. Shown on top of the 2D sets is the conventional 1D spectrum for this mixture.
