โฆ Synopsis
We describe a new multiple-pulse sequence (FLOPSY-8) for broadband homonuclear cross-polarization and compare it both theoretically and experimentally with the previous state of the art. FLOPSY-8 offers significant improvements in cross-polarization effkiency compared with the best alternative, and is especially useful for the large spectral bandwidths encountered in highfield carbon-l 3 NMR.

We have prepared RNAs uniformly 13C-labeled in the ribose ring and with the H3',H4',H5'/H5" protons specifically replaced with deuterons (3',4',5'/5"-2H-13C, termed d4-13C ribose), which offers the advantage of spectral simplification without sacrifice of sensitivity for the remaining protons. A 3D
