Photoabsorption cross sections for seven electric dipole-allowed N2 bands, at wavelengths between 95.8 and 99.4 nm, have been measured with an instrumental resolution of 6.2×10-4 nm. Integrated cross sections and band oscillator strengths are presented for the c4’ 1Σu+(v’=0)–X 1Σg’(v ‘=0) and c3 1Πu(v’=0)–X 1Σg+(v‘=0) transitions, as well as for five bands (v’=0,1,2,3,4) in the b 1Πu(v’)–X 1Σg+(0) progression. The results are compared with earlier, lower resolution absorption measurements, electron scattering measurements, and calculations based on a deperturbation analysis of the excited states.
