Comparison of finite pulse compensation schemes for HETCOR experiment. The homonuclear decoupling during t1 is executed by MSHOT4 pulses with finite pulse compensation scheme described by either (A) Nevzorov and Opella [25] or (C) Hohwy and Nielsen [24]. The corresponding spectra acquired on a NAL single crystal sample are shown on the right side (B and D). One-dimensional slices for the left-most peak were extracted for line width comparison. Compared to the NAL single crystal spectra in Figs. 2 and 4, the slightly larger line widths observed in these spectra is most likely due to the lower ¹H B₁ fields used in these experiments.
