### Optimal parametrisation of the Pariser-Parr-Pople Model for benzene and biphenyl

Abstract:

By means of exact diagonalisation studies of transition energies and oscillator strengths, we obtain an appropriate parameterisation of the Pariser-Parr-Pople hamiltonian for π-conjugated systems containing phenyl units, such as Poly-(para-Phenylene), Poly-(para-Phenylene-Vinylene) and their short chain oligomers. We do this by adjusting the parameters in the model to obtain an optimal fit to the experimental values of the low lying excitations of benzene, bi-phenyl and trans-stilbene. We use...
