The rotational wave packets of LiCl molecule excited non-adiabatically by half cycle pulse (HCP) is controlled using the second ultrashort HCP. By adjusting the time delay between the two laser pulses, constructive or destructive interference among these wave packets enables the population to be enhanced or repressed for the specific rotational state. The role played by the field strength and the pulse duration is also calculated numerically. We have used fourth order Runge-Kutta method to study non-adiabatic rotational excitation (NAREX) dynamics. Graphical Abstract Non-adiabatic rotational excitation and orientation of a polar LiCl molecule is studied by half cycle pulse (HCP) which is controlled by ultrashort HCP (UHCP). Both rotational excitation and orientation show strong dependence on duration of pulses and delay between pulses.
