The 13 C nuclear magnetic resonance (n.m.r.) spectrum of regioirregular poly (1-butene) with a large number of chemical inversion units in the chain was observed. The assignments were performed by 13C n.m.r. Lindeman-Adams empirical rules, the insensitive nuclei enhancement by polarization transfer (INEPT) and two-dimensional incredible natural abundance double quantum transfer experiment (2DINADEQUATE) 13C n.m.r, techniques. 2D-INADEQUATE was especially useful to assign each peak to carbon atoms located in several kinds of sequences in the chain.
