Electronic transition moments for the Lyman and Werner bands of the H2 molecule

We report new, more accurate ab initio values for the electronic transition moments of the B–X and C–X transitions of H2 in the internuclear distance range R=[1, 12 a.u.]. Most of the values published by Wolniewicz in 1969 are confirmed within 0.3% such that the resolution of a recently published discrepancy between experimental and theoretical B and C state lifetimes should be sought in the interpretation of the experimental measurements.
