We report on spectroscopic analyses of three K giants previously suggested to be Li-rich: IRAS 12327-6523, 13539-4153, and 17596-3952. High-resolution optical spectra and the LTE model atmospheres are used to derive the stellar parameters (T_eff, logg, [Fe/H]), elemental abundances, and the isotopic ratio ¹²C/¹³C. IRAS 13539-4153 shows an extremely high Li abundance of logε(Li)~4.2, a value 10 times greater than the present Li abundance in the local interstellar medium. This is the third highest Li abundance yet reported for a K giant. IRAS 12327-6523 shows a Li abundance of logε(Li)~1.4. IRAS 17596-3952 is a rapidly rotating (Vsini~35 km/s) K giant with logε(Li)~2.2. Infrared photometry shows the presence of an IR excess, suggesting mass loss. A comparison is made between these three stars and previously recognized Li-rich giants.
