Analysis of the origin of D-enriched molecules in the solar system indicates that low temperature chemical reactions present the most likely mechanism. These reactions could have occurred in the cooling solar nebula or in the interstellar clouds from which the solar system was later formed; low temperature is needed under both conditions, and neither equilibrium reactions nor kinetic effects can result in the observed ratios above temperatures of 200 K. The astronomical observations of even stronger D enrichments in molecules of dark interstellar clouds present important evidence that the second process was involved in the origin of D-enriched molecules.
