| Abstract: | Polarized absorption spectra of Ba(MnO4)2·3H2O/Ba(ClO4)2·3H2O mixed single crystals are reported at 4.2°K. Previous 1T2 → 1A1 assignments for the 5200 Å and 3000 Å absorption bands of MnO4? are substantiated; further support is provided for the 1T1 → 1A1 assignment of the 3600 Å absorption band of MnO4?. The site-splitting of the 5200 Å 1T2 state is E(1E)?E(1A) ≈ ?150 cm?1; that of the 3000 Å 1T2 state is E(1E)?E(1A) ≈ 300 cm?1. A significant e vibronic intensity component is observed in the 5200 Å 1T2 state. |
