The electronic ground state and the three first excited states of AgNH3 have been investigated theoretically. At the ab initio CASPT2 level, there is a quasi-degeneracy of the C3v minima of the 2A1 and 2E excited states (De=1.38 and 1.40 eV, respectively). While the 2E state displays a clear Ag(5pπ)+NH3 character, the nature of the 2A1 is more subtle, with both charge transfer and Rydberg characters. Semi-empirical introduction of the spin–orbit coupling enables the interpretation of a few features of the intricated R2PI spectrum.
