Performance of CP sequences against the HH mismatch (Δ= ω1C − ω1H) using a static adamantane sample: (a) CH2 peak and (b) CH peak. Crosses, open triangles, closed squares, and closed circles indicate the intensities obtained from CP, rampCP, COMPOZER-CP (Figure 1b), and the supercycled COMPOZER-CP (Figure 1c) experiments, respectively. The signal intensities were normalized by the maximum intensity of the CH2 or CH peak obtained in a CP. A contact time of 7.92 ms was used in all experiments.
