Abstract

Molecular hydrogen was studied spectroscopically using a frequency-doubled dye laser operating in the extreme ultraviolet (XUV, 86-90 nm) range. Crossed laser/molecular beam techniques were used for sub-Doppler resolution and 1 XUV+1 UV photoionization for sensitive detection applied in this study. The spectra of isolated and resolved rotational lines in the C¹Π_u-X¹Σ_g ⁺, B¹Σ_u ⁺-X¹Σ_g ⁺, D¹Π_u-X¹Σ_g ⁺, and B′¹Σ_u ⁺-X¹Σ_g ⁺ systems were recorded. The transition frequencies were obtained from an I₂-absorption spectrum in the visible domain using computerized interpolation procedures. The overall accuracy of linewidth measurements in the XUV domain was 0.04 cm^-1. These spectroscopic measurements improved classical (non-spectroscopic) measurements by a factor of 5.
