Isotopic Signatures of Presolar Materials in Interplanetary DustThese effects are most likely due to the preservation of presolar interstellar materials. While the elevated D/H ratios probably resulted from mass fractionation during chemical reactions at very low < 100 K temperatures, the origin of the N isotopic anomalies remains unresolved.

Elemental and Isotopic Abundances of Carbon and Nitrogen in Meteorites Primary phases, inherited from the solar nebula, are frequently isotopically heterogeneous, and surprisingly resistant to modification through parent body processing.

Transfer of the deuteron from H.D. can then lead to the efficient formation of multiply deuterated species, such as NHD. and ND..
