摘要：

ID NMR techniques for separately obtaining individual powder patterns for chemically distinct nuclei using selective rf irra- diation and switching of the spinner axis are proposed, which saves considerable time compared with the previous 2D approaches. A method has been applied for simultaneously obtaining all of the 13C chemical-shift powder patterns in p-diacetylbenzene. © 1990.
