13 C NMR studies are reported on enriched samples of a one‐unit model of the active centres present in butadiene polymerization. Concentrations between 2 × 10 3 M and 1M, and temperatures between −120° and 50° were investigated. The effect of ion‐pair association on charge distributions in diethyl ether solutions is described. The effect of temperature on the overall structure in tetrahydrofuran solutions is discussed.
