The electronic spectrum of thiophene has been studied using multiconfiguration second-order perturbation theory and extended AN0 basis sets. The calculations comprise four singlet valence excited states and the 3s3p3d Rydberg series. The lowest triplet states were included and some n-n\* and n-ti st
