镧系位移试剂被认为是70年代核磁共振五大进展之一。在图谱一级化、吸收峰归属及立体结构测定等方面有很多应用。镧系位移试剂用于立体结构的测定,曾号称是“溶液中的X射线测定”。但其基础不太巩固。因为,将位移试剂用于立体结构测定需要正确解决三个 Lanthanide shift reagents are considered as one of the five major advances in the 1970s. In the spectrum of a level, the absorption peak attribution and determination of three-dimensional structure has many applications. Lanthanide shift reagents for the determination of the three-dimensional structure, once known as the “solution in the X-ray determination.” But its foundation is less solidified. Because, the use of displacement reagents for the determination of three-dimensional structure need to correctly solve the three
