Abstract

It is argued that photochemical processes, driven by ultraviolet starlight, could lead to large deuterium fractionation for H_2O and CH_4 relative to H_2 in the primitive solar nebula. Implications for deuterium enrichment observed in planetary atmospheres are briefly discussed.

We thank R. G. Prinn for pointing out the potential importance of starlight as a means for initiating photochemistry in the Solar System. This work was partly inspired by G. J. Wasserburg's grandiose vision of geochemistry and cosmochemistry in our division although there is no conceivable correlation between this humble research and his grandiose vision.
