摘要：

The nmr spectra of fluorenyl lithium, sodium, potassium, and rubidium have been analyzed in terms of chemical shifts and coupling constants. Cation has no effect on the coupling constants. Chemical shifts of the carbanion appear to lower field with increasing charge/radius ratio of the cations with lithium being an exception. The results are discussed in terms of bonding properties of the cations and of the types of ion pairs formed with the cations.
