Synthetic spectra and MCMC analysis establish deuterium detection limits in early-type stars as a function of SNR, Teff, and v sin i, with upper limits D/H < -5.5 dex for HD 32115 and < -4.9 dex for 21 Peg.
NLTE analysis finds F_odd of 0.65 in one CEMP-rs star versus 0.23 in two CEMP-s stars, supporting distinct isotope ratios as a signature of different neutron-capture processes.
