The authors conduct a comprehensive line analysis of the NMR spectra of a number of polymers, including cis-1,4-polyisoprenes, cis-1-4-polybutadiene, polyisobutylene, and polyethylene, in a deuterated benzene solvent. Data are given on hyperfine structure and spin-spin coupling constants along with conformational behavior and a negative Overhauser effect observed in the isomers.
