Laboratory experiments and theoretical modeling show that the chemistry of chlorine is fairly simple in dense interstellar clouds, with Cl and HCl as the only species whose fractional abundances are significant. The estimated fraction of gas-phase chlorine present as HCl lies between 25%-65%, in good agreement with the recent observations of the ground state HCl transition by Blake, Keene, and Phillips. These results, combined with the observational limits on HCl, indicate that chlorine is not severely depleted in dense interstellar clouds.
