Using ultrahigh-resolution 1 XUV+1 UV two-photon ionization laser spectroscopy, the F (3)Pi(u)<- X (1)Sigma(g)(+)(0,0) transition of N-2 has been optically observed for the first time, and the 3s sigma(g)F (3)Pi(u)(upsilon=0) Rydberg level fully characterized with rotational resolution. The experimental spectroscopic parameters and predissociation level widths suggest strong interactions between the F state and the 3p pi(u)G (3)Pi(u) Rydberg and C-' (3)Pi(u) valence states, analogous to those well known in the case of the isoconfigurational (1)Pi(u) states.
