โœฆ Synopsis

Local orientational order in liquids and solids is eumined using rhe average "distribution of cosines" of angles subtended at pxticlcs in the liquid by pairs of nearest-neighbour particles. a technique fit introdurrd by Scott and \ladrr. This average information is compared with recent, more complete theories and simulations of orientational order. The lowest-order approximation to the "distribution of cosines" is shown to fail for dense systems. but the true distribution m3y mawred wry efficiently in computer simulations. * Note that hlountain and Basu [ 71 distinguish first and second nekhbours in the bee crystal.

Solid state nuclear magnetic resonance has the potential to characterize membrane protein structures at very high resolution. This paper focuses on the use of orientational constraints for this purpose. These constraints are based on observing the orientation dependence of nuclear spin interactions.
