We present a theoretical study of the rotational dynamics of asymmetry top molecules in parallel electric field and non-resonant linearly polarized laser pulses. The time-dependent Schr\"odinger equation is solved within the the rigid rotor approximation. Using the benzonitrile molecule as prototype, we investigate the field-dressed dynamics for experimentally accessible field configurations and compare these results to the adiabatic predictions. We show that for an asymmetric top molecule in parallel fields, the formation of the pendular doublets and the avoided crossings between neighboring levels are the two main sources of non-adiabatic effects. We also provide the field parameters under which the adiabatic dynamics would be achieved.
