Bromine (Br) and iodine (I) are chemical species that play central roles in polar atmospheric chemistry, ozone depletion, and cloud condensation nuclei formation and the natural sources to the atmosphere is the ocean1. In particular, bromine undergoes a series of autocatalytic reactions that lead to...
