The lithium abundance in the atmospheres of eight giants of the spectral class K5-M3 has been determined with allowance for molecular absorption. Spectrograms of the stars were obtained using the 2.6-m telescope of the Crimean Astrophysical Observatory with reciprocal dispersion 6 A/mm. To take into account the molecular absorption, synthetic spectra in the region 6700-6710 A were calculated by means of Tsuji models (1978). The models include all known atomic lines and bands of the molecules TiO, CN, and ZrO. In the atmospheres of six of the eight stars there is a deficit of the lithium abundance; in the atmosphere of 3 Aqr M3 III the lithium abundance has the solar value, while in 29 Cap M3 III a lithium excess is found.
