Deuteration enhancement in TMC-1 for selected molecules compared to our gas-phase chemical model.
|Model (a)||Model (a)||Model (a)|
|Molecule||TMC-1||N/O = 0.5||N/O = 1||N/O = 1.5|
See text for the assumed physical conditions. [O/H] = 8 × 10−6, D/H = 1.5 × 10−5, and C/O = 0.75.
These H/D abundance ratios are from Cernicharo et al. (2020c).
