We have studied the spectra of UU Her stars 89 Her and HD 161796 in the red spectral region. The atmospheric parameters are derived using model atmospheres and spectrum synthesis. LiI line at 6707.8 A° is identified and measured in 89 Her leading to log (Li/H) = 2.3. The variation of the Hα line profile for these stars is also discussed.
