✦ Synopsis

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. KEY WORDS 2D powder pattern Polypropylene Off-magic angle spinning Chemical shift principal values Chemical shift principal axis directions

We demonstrate a dipolar-chemical shift correlation technique for sign-sensitive determination of the torsion angle in solid peptides and proteins under magic-angle spinning. The indirect dimension of the experiment is obtained by separate but synchronous evolution of the magnetization under the 15
