(color online) The electronic dipole acceleration (red dotted line), the nuclear dipole acceleration (violet dashed-dotted line), and the total dipole acceleration (black solid line) for (a) HD and (b) HeH. For clarity, is amplified by times. (c) Harmonic spectra generated from HD. Black solid line is calculated with , and red dotted line is calculated with . (d) Same as panel (c) but for HeH.
