Abstract
The electronic and magnetic circular dichroism spectra of thin layers of Cu1 and AgI halides have beem measured at low (~ 10 K) temperatures. The mcd spectra show clearA-terms which, in the case of the silver halides and for one band of cuprous iodide, have unexpected negative signs. A qualitative theoretical interpretation of these signs has been attempted by considering halogen-p and metals/d atomic orbital mixing within the framework of a simple, tight-binding model. Reasonable agreement of theory with experiment has been achieved for the positive copper halideA-terms, but it has not proved possible to obtain by calculation the experimentally observed negativeA-term sign of the silver salts and cuprous iodide.
