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 C1Πu-X1Σg +, B1Σu +-X1Σg +, D1Πu-X1Σg +, and B′1Σu +-X1Σg + 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.
