Abstract: We derive formulas and perform calculations of nonadiabatic corrections to rates of electric quadrupole transitions in the hydrogen molecule. These corrections can be represented in terms of a single curve D(1)(R), similarly to the Born-Oppenheimer one, D(0)(R), derived originally by Wolniewicz. Numerical results change E2 transition rates for the fundamental band by as much as 0.4–12% depending on rotational quantum numbers.
