Optical absorption spectra of Li1−xNaxBr and Li1−xMxI (M=Na, K, and Rb) measured at liquid nitrogen temperature are reported. In the systems of iodides, the persistent behavior of the first exciton bands is clearly observed. This nature is discussed in connection with the theory of mixed crystals. In Li1−xNaxBr the spectral shape changes abruptly at 0.46≤x≤0.50. In all the systems, additional sharp band is observed on the low energy side of the first exciton band of lithium halides when the concentration of doped alkali ion is less than 10%.
