Absorption Spectrum of LiI: Tl

Abstract

The C band of LiI: Tl is considerably depressed. The ratio in area of the C band to the A band of LiI: Tl is 2.8 which is smaller than those in NaI: Tl, KI: Tl and RbI: Tl. Magnitude of splitting between the C and D bands of LiI: Tl is the largest among these four phosphers. These results suggest that in LiI: Tl there exists strong configuration interaction between two states corresponding to the C and D bands.
