Abstract Tunable, narrowband extreme ultraviolet radiation in the range 90.5–95 nm with only limited intensity variations is produced by frequency-tripling ultraviolet light from a frequency-doubled dye laser in a gas-jet of xenon. Acetylene gas is found to be an efficient medium for third-harmonic generation in this wavelength range as well. The extreme-ultraviolet radiation is applied in a spectroscopic study of the b 1 II u , v=6−8 and v=10−12, o 1 II u , v=0 and b′1Σ u + , v=9 states of molecular nitrogen. From linewidth measurements a value k p=6×1010 s−1 for the predissociation rate of the b 1 II u , v=11 state is deduced.
