    "abstract": "We study the dynamics of the populations of a model molecule endowed with two\nsets of rotational levels of different parity, whose ground levels are energy\ndegenerate and coupled by a constant interaction. The relaxation rate from one\nset of levels to the other one has an interesting dependence on the average\ncollision frequency of the molecules in the gas. This is interpreted as a\nquantum Zeno effect due to the decoherence effects provoked by the molecular\ncollisions.",
