A 13 C spin‐echo technique with gated 6 Li decoupling has been developed for the selective observation of different alkyllithium aggregates, (RLi) n . The spectral editing technique is based on the fact that both the multiplicity of the 13 C resonance and the magnitude of the observed 13 C 6 Li coupling are a function of the number of coupled 6 Li nuclei. The method was shown to differentiate between three types of tert ‐butyllithium‐ 6 Li: dimers, fluxional tetramers and non‐fluxional tetramers.
