Query: Analyzing laser-induced alignment of weakly-bound molecular aggregates   The rotational and torsional dynamics of the prototypical floppy
$\text{indole}(\text{H}_2\text{O})$ molecular cluster was theoretically and
computationally analyzed. The time-dependent Schr\"odinger equation was solved
for a reduced-dimensionality description of the cluster, taking into account
overall rotations and the internal rotation of the water moiety. Based on our
results, it became clear that coupling between the internal and the overall
rotations are small, and that for typical field strengths in alignment and
mixed-field orientation experiments the rigid rotor approximation can be
employed to describe the investigated dynamics. Furthermore, the parameter
space over which this is valid and its boundaries where the coupling of the
internal and overall rotation can no longer be neglected were explored.
