Abstract
The absorption spectrum of the H2 molecule has been studied in the wavelength region 930–840 Å with a 6.8‐m grazing incidence vacuum spectrograph in combination with the helium continuum. The Lyman and the Werner bands have been extended to their dissociation limits. The results of the rotational analysis of these bands are given. Behavior of the C 1Πu potential curve near the dissociation limit and predissociation found in the v = 13 level of the C state are also discussed.
