| Popis: | Zeeman and site selective luminescence and excitation spectra in the region of the 2E--4A2 transition are reported for the hexaaquachromium(III) complex in the trigonal ferroelectric guanidinium aluminum sulfate hexahydrate. The two prominent transitions are due to the R1 lines of the two sites of C3 and C3v point symmetry. The two R1 lines display g parallel = -3.1 and g parallel = -3.2, respectively, and show no measurable Zeeman shift or splitting with B perpendicular c. This behavior is consistent with the presence of a very large trigonal field. A peculiar feature of the present system is the conspicuous absence of any prominent R2 line. From the Zeeman data with B perpendicular c and a comparison of vibrational sidelines in excitation and luminescence it is concluded that the R2 level strongly interacts with vibrational levels. |
