The effects of hydrogen bond interactions upon ionization potentials (IPs) and electron affinities (EAs) of adenine–formamide (AF) complexes have been investigated employing the density functional theory B3LYP. It is found that the hydrogen bond interactions between adenine and formamide play a more important role in the process of electron attachment than in the process of electron detachment. Meanwhile, the hydrogen bond interactions facilitate the adiabatical electron detachment and attachment but have different effects on the vertical electron detachment and attachment with different positions of formamide. Furthermore, when the complexes were dissociated to the free monomers, the processes AF - → A - + F and AF + → A + + F are energetically preferable for AF- and AF+, respectively.
