ON THE INFERENCE OF THE COSMIC-RAY IONIZATION RATE ζ FROM THE HCO<sup>+</sup>-to-DCO<sup>+</sup> ABUNDANCE RATIO: THE EFFECT OF NUCLEAR SPIN
ABSTRACT The chemistry of dense interstellar regions was analyzed using a time-dependent gas–grain astrochemical simulation and a new chemical network that incorporates deuterated chemistry, taking into account nuclear spin states for the hydrogen chemistry and its deuterated isotopologues. With this new network, the utility of the [HCO + ]/[DCO + …
