Correlated-electron theory of triplet–triplet multiexciton states in polypentacene

We present correlated-electron calculations of optical spin-singlet and triplet-triplet multiexciton states in three- and four-unit pentacene oligomers as microscopic models for polypentacene. The calculations use the Pariser-Parr-Pople Hamiltonian, multiple-reference singles and...
