Abstract
The emission spectrum of [Cr(urea)(6)]I-3 single crystals excited unde r resonance condition into the zero phonon (4)A(2g)-->E(1/2)((2)E(g)) absorption line, which is inhomogeneously broadened from 14210 to 1424 0 cm(-1), is recorded at 1.9 K. The vibrational sideband spectrum is s hifted in a characteristic way, the spectral profile being changed onl y in some minor details. All features can be explained by energy trans fer processes between majority and minority complex species which have small differences of transition energies in the crystal.
