  Coherent control of chaotic molecular systems, using laser-assisted alignment
of sulphur dioxide (SO$_2$) molecules in the presence of a static electric
field as an example, is considered. Conditions for which the classical version
of this system is chaotic are established, and the quantum and classical
analogs are shown to be in very good correspondence. It is found that the chaos
present in the classical system does not impede the alignment, neither in the
classical nor the quantum system. Using the results of numerical calculations,
we suggest that laser-assisted alignment is stable against rotational chaos for
all asymmetric top molecules.
