Magnetically Induced Circular Emission-Spectrum Of Cr(Iii) In Guanidinium Aluminum Sulfate

The magnetically induced, circular emission spectrum (MICE) of Cr(III) in hexagonal guanidinium aluminium sulphate hexahydrate has been measured together with the axial emission spectrum. Four lines are observed in the 2 E region suggesting that these are the result of trigonal field and site symmetry splittings since each component exhibits an A term type dispersion. The MICE spectrum enables several of the vibrational features to be identified.
