Abstract
The influence of including electron correlation on structural and electronic properties for a prototype infinite π-conjugated system was studied using the MP2 scheme. The equilibrium geometry, the energy band gap, force constants, and vibrational frequencies were successfully taken into account. Further, it was shown that electron correlation corrections at the MP2 level have a large impact on these properties.
