Abstract

The c′₄¹∑⁺_u, v = 0 and c₂¹Π_u, v = 0 Rydberg states of N₂ are studied by means of 1 XUV + 1 UV resonance enhanced two-photon ionization. The experimental resolution (0.35 cm^-1 fwhm) combined with a calibration against a visible wavelength I₂ standard results in an order of magnitude better accuracy in the absolute line positions than in previous non-laser based investigations. The effects of homogeneous and heterogeneous perturbations of the Rydberg states by b′ ¹∑⁺_u and b′ ¹Π_u valence states are analyzed.
