The structural and electronic properties of perfluorinated surfactants perf
luorooctane sulfonate (PFOS) and lithium perfluorooctane sulfonate (LiPFOS)
have been investigated theoretically by performing semi-empirical molecula
r orbital theory at the level of AM I calculations. The optimized structure
and the electronic properties of the molecules are obtained. (C) 2001 Else
