Wave packets describe the quantum vibrations of a molecule. They are highly oscillatory, highly localized and move in high dimensional configuration spaces. The governing equation is the time-dependent Schr\"odinger equation in the semiclassical regime. The talk addresses three meshless numerical methods for catching wave packets: single Gaussian beams, superpositions of them, and the so-called linearized initial value representation.
