The ratios of the radiative transition probabilities for the lines of the P, Q, and R branches of the (4d)r 3Π g - , (4d)s 3Δ g - → (2p) c 3Π u ± band systems of the H 2 molecule have been measured for the first time. Significant (to two orders of magnitudes) differences are found between the experimental values and the adiabatic theory predictions. It is established that the results of the nonadiabatic calculation performed by us in the pure-precession approximation taking into account the electronic-rotational interaction of the 4d 3Πg and 4d 3Δg states are in agreement with the experimental data. The optimal energies of rovibronic levels of the r 3Π g - , s 3Δ g - , c 3Π u - , and c 3Π u + states have been found and reidentification of 11 from 54 spectral lines, assigned previously to the (0-0) and (1-1) bands, was performed.
