The two-dimensional powder pattern for isotactic polypropylene in a sample rotating at an off-magic angle has been measured and the chemical shift principal values and principal axis directions for each of the CH, CH, and CH, carbons, together with their C-H bond lengths, have been determined.

The orientations of the 13C chemical shift tensors in undoped cis-and tram-polyacetylene have been determined from the chemical shift-dipolar two-dimensional powder patterns observed in rotating samples.
## Abstract Twoβdimensional heteronuclear chemical shift correlation experiments which attempt decoupling in __f__~1~ have been shown to give artifacts in strongly coupled systems. In particular, COLOC and HETRES experiments on methylene groups show an artifact midway between the two proton lines.
