Carbon-13 NMRspectra of the η6-fluorenyl complexes (fluorene- (I), 3-methylfluorene- (II), and 6-methylfluorenechromium tricarbonyl (III) are described by the means of the “fingerprint” method, 13C spin-lattice relaxation time measurements, and an additive calculation of carbon chemical shifts of the methyl-substituted complexes (II,III). This sequence of operations can be used to analyze 13CNMR spectra
碳13的η的NMR谱6 -芴基复合物(芴(I),3- methylfluorene-(II),和6- methylfluorenechromium三羰基(III)是由“指纹”方法的装置所描述的,13 Ç旋晶格弛豫时间测量,以及甲基取代的配合物(II,III)的碳化学位移的加法计算,该操作顺序可用于分析相关的多芳族过渡金属配合物及其异构体混合物的13 C NMR光谱相同或不同结构类型的物种。
