Notes:
Abstract Emission and absorption polarization spectra as well as emission lifetimes between room temperature and 5 °K have been measured of [Cr urea6]X3 single crystals, where X stands for ClO 4 − , J−, NO 3 − , Br−, Cl−, F−, and X3 for JSO 4 3− . The strong temperature dependence of the fluorescence/phosphorescence-ratios, and of the emission lifetimes is discussed. The differences between the spectra as well as the emission lifetimes of the various salts can be attributed to an anion dependent trigonal perturbation.
