N2 - The nonadiabatic model developed by us earlier was used to calculate absolute values of probabilities of spontaneous J1Δg- v', N → B1 transitions of the H2 molecule for the vibrational quantum numbers v' = 0-3, v" = 0-9 and the rotational quantum numbers N=2-6. In the calculations, we used the values of coefficients of the expansion of the wave function of radiative states in the Born-Oppenheimer basis of the 3d1Πg- and 3d1 Δg states of the H2 molecule and the dependence of the transition dipole moment of the 3d1Πg → 2p1Σu+ electronic transition of the hydrogen molecule on the internuclear distance, which had been obtained by us earlier semiempirically. The semiempirical values of probabilities of these transitions were compared with the values calculated with the help of ab initio data on the transition dipole moment of the 3d1Πg → 2p1Σu+ electronic transition. The nonadiabatic effects in the probabilities of spontaneous J1AΔg-, v', N → B1Σu+, v", N transitions of the H2 molecule were analyzed.
