The 13 C NMR spectra of models for the initial and terminal monomeric unit diads of polybutadiene are interpreted. The models are C 10 H 18 , diolefins, separated from the mixture of oligomers which are formed in the reaction of buta‐1,3‐diene with ethyllithium and a proton donor. A version of the INADEQUATE pulse sequence with DEPT polarization transfer and a selective DANTE read pulse is described and used for assignment.
