摘要：
An experiment which separates H-2 spinning sideband patterns according to the H-2 double-quantum chemical shift in a manner suitable for motional studies is proposed. The technique is successfully applied to 4,4'-azoxydianisole at 323 K to separately analyze the motion of the aromatic and-methyl deuterons. Comments are made on the formation of a nematic mesophase in this material at 390 K in the light of the results of this NMR study. (C) 1997 Academic Press.
