For molecules in high intensity oscillating electric fields, the time-dependent Hartree–Fock
(TDHF) method is used to simulate the behavior of the electronic density prior to ionization …

Bond hardening of H 2+ has been observed in the intensity range of 100–200 TW/cm 2
using 792 nm laser pulses. This effect can be understood in terms of a light-induced …

We present a photodissociation experiment on H 2+ with ultrashort laser pulses (≥ 130 fs)
at peak intensities of≤ 1.5× 10 14 W/cm 2. Since in an ion beam setup H 2+ is produced in a …

H 2 molecules were ionized by Ti: sapphire (45 fs, 800 nm) and Nd-doped yttrium aluminum
garnet lasers (6 ns, 1064 nm). The relative populations of the vibrational levels of the H 2+ …

The fragmentation of the H 2+ molecular ion in 25-fs, 800-nm laser pulses in the intensity
range 0.05–0.5 PW/cm 2 is investigated by means of wave-packet propagation calculations …

Time-dependent Hartree-Fock (TD-HF) and time-dependent configuration interaction (TD-
CI) methods with Gaussian basis sets have been compared in modeling the response of …

Intramolecular electronic dynamics and tunnel ionization of H 2 in an intense laser field (I≈
10 14 W/cm 2 and λ= 760 nm) are examined with accurate evaluation of three-dimensional …

Modeling the dynamics of non-bound states in molecules requires an accurate description of
how electronic motion affects nuclear motion and vice-versa. The exact factorization (XF) …

We present a new method to extract momentum distributions from time-dependent
wavepacket calculations. In contrast to established Fourier transformation of the spatial …

A number of different levels of theory have been tested in TD-CI simulations of the response
of butadiene interacting with very short, intense laser pulses. Excitation energies and …
