Abstract
Luminescence spectra and photoselection spectra have been measured for some Cr(III) complexes having molecular D 3 symmetry including Cr(exan) 3, Cr(dmtc) 3, and Cr(acac) 3. the photoselection data is consistent with an intensity mechanism for emission involving a pure spin-orbit mixing of the quartet and doublet manifold; however, the results are not conclusive. The photoselection spectra for the Cr(dmtc) 3 complex, for which an unusual hybrid fluorescence-phosphorescence has been observed, implies that this emission is occurring from a single potential surface rather than an overlapped dual emission resulting from separate quartet and doublet excited states.
