Spin-orbit coupling in nitrite ion and nitrite salts


The absorption intensity of the3B11A1 transition of nitrite salts of the non-transition metals is markedly dependent on the metal counterion and is causative of the yellow-orange colors of the heavier-metal salts. It is assumed that spin-orbit coupling is responsible for this phenomenon; this assumption is investigated here using semi-empirical one-electron calculations and is validated. The subjects of covalent bonding in metal salts, charge transfer transitions in such systems and the S j ← S 0 electronic spectroscopy of nitrite salts are also investigated.
