We study the problem of excitation of molecules by an ultrashort laser pulse sequence by the use of path-integral approach in energy states space. Using numerical calculations of path-integral we evaluate laser field parameters at which there are quantum resonances in rotational dynamics of dinitrogen isotopes. So we describe recent experimental results [Phys. Rev. Lett. 109, 043003 (2012)] theoretically.
Key words: path integral / rotational excitation of molecules
