A variety of radicals have been identified by e.s.r. in γ-irradiated hydrates of Group IIA chlorides. These include a Cl2– centre in SrCl2,6H2O which is notable in having two inequivalent chlorine atoms (A∥= 109·1 G for Cla and 94·9 G for Clb), and a centre thought to be ClOH– in BaCl2,2H2O, which is isostructural with the VK-centres. Trends in the hyperfine parameters for these and related centres are discussed in terms of the electronegativities of their constituent atoms.
