Abstract
We study the problem of rotational excitation of molecules by an ultrashort laser pulse sequence. Recent experimental investigations [Phys. Rev. Lett. 109, 043003 (2012)] shows that there are quantum resonances in rotational dynamics of dinitrogens molecules for some values of pulse train period. We describe these results theoretically. Physical parameters of ultrashort laser pulse sequence for effective selective rotational excitation of dinitrogens isotopes were defined by numerical simulations.
