    Notes: 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.

    High-resolution laser spectroscopy on H2 at 97–98 nm (1994)

    Notes: Abstract A narrowband tunable eXtreme UltraViolet (XUV) laser source is used for a high resolution study of the Lyman (B 1 Σ u + ™X 1 Σ g + ) band system of molecular hydrogen. Seven rotational transitions of two vibrational bands, (10,0) and (11,0), in the wavelength range from 97.2–98.3 nm have been investigated for the first time under sub-Doppler molecular beam conditions. A calibration procedure using the I2 standard in the visible yielded an absolute frequency accuracy of 0.02 cm−1. The obtained H2 transition frequencies provide a calibration standard in the extreme ultraviolet wavelength region.
