Bromide can thus inhibit the in-cage recombination between {\^a}?cOH and {\^a}?cNO2. The consequence is an increased generation of {\^a}?cNO2 and nitrite and of Br2 -{\^a}?c + {\^a}?cOH, compared to {\^a}?cOH alone in the absence of bromide. We show that this effect compensates for the lower reactivity of Br2 -{\^a}?c compared to {\^a}?cOH toward certain organic substrates, e.g. phenol and tryptophan. Our findings could lead to a deep revision of the present views of the role of bromide in saltwater photochemistry. {\^A}{\copyright} 2008 Springer-Verlag.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-71249134884&doi=10.1007\%2fs10311-008-0176-8&partnerID=40&md5=ea70ba60146e354438deaa3fd5520799} }
