Molecules are quantum objects, and so many aspects of their dynamics are poorly described by Newton's laws of motion. With a full quantum treatment unfeasible for all but the smallest systems, approximate descriptions have to be developed. My work is concerned with path-integral based approximations that allow to rigorously combine zero-point energy effects and tunnelling with classical dynamics. A particular focus is furthering the theoretical understanding of existing methods (CMD, [T]RPMD), with the outlook of improving on such approximations, especially in simulations of rovibrational spectra.
