FIG. 12: HHG spectra for H2 computed at the TDHF/5-aug-cc-pVTZ level from a continuous-wave simulation with CAP parameters r 0 = 9.524 bohr and η = 4.0 Ha/bohr 2 . The total simulation time of 5,000 a.u. has been divided into five consecutive segments of 1,000 a.u. each and the spectra in panels (a)-(e) are obtained from the Fourier transform of the dipole moment data within each segment, as indicated. The intensity scale, which is logarithmic, is the same in each panel.
