It has been known that electronic conical intersections in a molecular system can
also be created by laser light even in diatomics. The direct consequence of these
light-induced degeneracies is the appearance of a strong mixing between the electronic
and vibrational motions, which has a strong fingerprint on the ultrafast nuclear dynamics.
In the present work, pump and probe numerical simulations are performed with the NaH
molecule involving the first three singlet electronic states (X1 sigma+(X), A1 sigma+(A)
and B1 pi(B)) and several light-induced degeneracies in the numerical description.
To demonstrate the impact of the multiple light-induced non-adiabatic effects together
with the molecular rotation on the dynamical properties of the molecule, the dissociation
probabilities, kinetic energy release spectra (KER) and the angular distributions
of the photofragments were calculated by discussing the role of the permanent dipole
moment as well.It has been known that electronic conical intersections in a molecular
system can also be created by laser light even in diatomics.
