Abstract
The electronic spectra, in the visible and u.v. regions, of HgX3 –(X = Cl, Br, or I) have for the first time been obtained, by a computer technique, free from any contributions of HgX2 or HgX4 2–, and the resolved bands are assigned and permit identification of HgCl3 – as planar with D3h symmetry, and HgI3 – as pyramidal, with C3v symmetry, which suggests that the solvated species are trigonal-bipyramidal and tetrahedral, respectively; HgBr3 – has possibly intermediate or pyramidal geometry.Keywords
