Tracing the vibrational dynamics of sodium iodide via the spectrum of emitted photofragments

Abstract

We study by real-time wave packet simulations the ultrafast photodissociation dynamics of the sodium iodide molecule with the aim to trace molecular vibrational motion in a bound electronic state. Applying...

Attosecond Probing of Nuclear Vibrations in the D2+ and HeH+ Molecular Ions

“…We envision that the multipeak pattern in the KER results from the temporal interference of nuclear wave packet amplitudes that are emitted with the same energy but with a certain time delay during the action of the probe pulse. The emergence of such a dynamic interference pattern in the KER spectrumwhich is consistent with our previous modelis clearly disadvantageous, as it is reflected in the recovered density and thus prevents a perfect mapping.…”

“…Most of the probing techniques are customized to monitor molecular motion in excited states after optical or (X)­UV pumping. In general, it is more difficult to induce significant structural changes in the ground electronic state using pulsed laser excitation. , The dynamic Stark control (DSC) of potential energy surfaces is often applied to prepare initial wave packets and manipulate the nuclear wave packet motion − or the photoexcitation probability . In this regard, simple polar diatomic molecules with large permanent dipoles, like HeH + , are important showcase systems for studying DSC-related processes.…”
