AB - <p style="text-align: justify;">Multiphoton ionization of the $Na_2$ molecule by a single phase shaped femtosecond 
laser pulse has been theoretically studied using time-dependent quantum wave packet 
method including the effect of molecular rotation. We analyze the temporal development 
of the population and further discuss the molecular motion by mapping the rovibrational 
wave packet propagation in the excited state. The calculated results show a strong 
dependence of the kinetic energy-resolved photoelectron spectra on the laser chirp 
directions and the pulse duration.</p>
