Popis:	A re-examination of the luminescence and absorption spectrum of Cr(urea)6I3 and Al(urea)6I3: Cr(urea)3+6 shows that the diluted material contains local concentrations of Cr(urea)3+6 ions within which energy transfer processes from majority sites to minority sites occur. These processes also occur in pure Cr(urea)6I3. The absorption spectrum may be completely analysed as 4A2→2E, 2T1 electronic origins together with vibronic origins involving vibrational intervals similar to those observed in the luminescence, infrared and Raman spectra.
