We apply a method suggested by Delos [Rev. Mod. Phys. 53, 287 (1981)] to correct the Born-Oppenheimer basis by incorporation of proper boundary conditions for bound states of molecular systems. We calculate the correct nonadiabatic coupling matrix elements for [Formula Presented] and its isotopic variants and use them to determine the [Formula Presented] vibronic spectrum.
