Notes:
The phase cycle for the FLOCK experiment was modified to provide improved suppression of artifacts and improved signal-to-noise ratios. An alternative version of FLOCK in which the initial BIRD pulse during t1 is replaced by a one-step J filter is shown to give comparable performance, while a phase-sensitive version of FLOCK shows the expected \documentclass{article}\pagestyle{empty}\begin{document}$ \sqrt 2 $\end{document} increase in sensitivity. Finally, while it is shown that phase-sensitive FLOCK without decoupling during acquisition can be used to measure nJ(C,H) (n ≤ 2), there are serious limitations to this approach.
