Abstract
The position and the intensities of the Q lines of the absorption spectrum of H2 were studied in the 81-72 nm wavelength range, using synchrotron light. The transition probabilities of the npπ 1Π-u v, J - X1Σ+g v'' = 0, J'' = J = 1 transitions with 3 ≤ n ≤ 12 have been measured and compared to calculated values. A good agreement has been found. The main discrepancies observed may well be related to local non-adiabatic couplings not included in the calculations. Vibrational couplings between levels with large Δv values up to Δv = 5 were observed affecting the transition probabilities.
