The structure and dynamics of hydrogenated oligo(cyclopentadiene) (HOCP) was investigated by means of 1H and 13C NMR in the solid state. The 13C NMR spectrum of HOCP is reported and interpreted for the first time here. Quantitative information on the distribution of the different structural and diastereoisomeric environments of the cyclopentane monomers was thus obtained. Moreover, the dynamic behavior of HOCP was investigated through the measurements of 1H and T1p, and T1, as well as 13C T1 relaxation times, highlighting the presence of two major motional processes, whose specific nature is discussed. Quantitative dynamic parameters were extracted by applying suitable theoretical models to the 1H T1 curve vs temperature.
