Abstract

In [Cr(urea-h₄)₆](ClO₄)₃ the lowest sublevel of 4T2g(t2g2 eg1) lies ΔE=90±10 cm⁻¹ above the lower 2Eg(t2g2) sublevel. At 1.3 K one observes a fine-structured phosphorescence. With temperature increase, for example to 120 K, the quartet is thermally occupied and one obtains a broad-band fluorescence. Pressure application at the same temperature results in a blue-shift of 4T2g relative to 2Eg. This ...
