✦ Synopsis

Interleaved sideband families that arise from distinct isotropic chemical shifts and the associated chemical shift anisotropy (CSA) tensors in magic angle spinning NMR are conventionally disentangled using two-dimensional schemes. However, for the case of just a pair of distinct chemical sites, a scheme is suggested that involves a pair of one-dimensional experiments whose sum and di †erence spectra separate the interleaved sideband families. This method was applied to phospholipid bilayers. The 31P NMR sidebands of phosphatidylcholine and dioleoylphosphatidylethanolamine are separated and CSA values for each phospholipid were calculated.

A robust magic-angle-spinning experiment for separating undistorted, quasi-static chemical-shift powder patterns is presented. It is derived from the technique of R. Tycko, G. Dabbagh, and P. Mirau (1989, J. Magn. Reson. 85, 265), but uses 360 • instead of 180 • pulses. In combination with a suitabl
