The density functional theory has been used for calculating the structures and vibrational wavenumbers of the radical anion and cation of biphenyl. The radical anion has a planar structure, while the radical cation is twisted. Upon ionization, structural changes occur in the direction from benzenoid to quinoid. Unsealed wavenumbers calculated at the Becke-Lee-Yang-Parr/6-31G* level are mostly in agreement with observed vibrational wavenumbers in the literature.
