摘要：

The C-13 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 C-13 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 (2D-INADEQUATE) C-13 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.
