We consider a chiral molecule modeled by two sets of rotational internal energy levels of different parity and degenerate ground states coupled by a constant interaction. By assuming that the collisions in a gas of identical molecules, provoke transitions between adjacent energy levels of the same parity, we apply the prescriptions of the continuous time quantum random walk to a single molecule, interpreted as an open quantum system, and build up the master equation driving its internal dynamics in case of a general distributions of collision times. The asymptotic exact dynamics of the coherence terms and the populations of the energy levels are analytically evaluated for relevant classes of non-Poissonian distributions of the collision times. The inverse quantum Zeno effect and inverse power law relaxations emerge over estimated long time scales.
