“…The ability of the present approach to capture essential aspects of excited-state physics under a strong external field, will pave the way for further theoretical investigations of nonlinear processes involving excited molecular states. To mention a few recent applications, this could, for example, include investigations of the role of highly-excited molecular states in analysis of multiphoton-induced free-induction decay in Stückelberg spectroscopy [27] or in high-order harmonic generation by counterrotating circularly polarized fields [28].…”

We present theoretical results for intensity-dependent above-thresholdionization (ATI) spectra from oriented OCS molecules probed by intense femtosecondlaser pulses with wavelengths of 800 and 400 nm. The calculations were performedusing the time-dependent Schr¨odinger equation within the single-active-electronapproximation and including multielectron polarization effects. The results capturesome of the experimental findings [Yu et al., J. Phys. B: At. Mol. Opt. Phys. 50,235602 (2017)], in particular when considering the sensitivity of the ATI spectra onthe molecular orientation. We identify characteristic features in the ATI spectra whichcorrespond to resonant multiphoton ionization via highly-excited Rydberg states arecaptured by the theory
