Abstract
The basicity of alkali-exchanged zeolites has been characterized by ch loroform adsorption using FTIR spectroscopy. The chloroform is adsorbe d on the basic oxygen site through its hydrogen atom, while a weak int eraction also exists between the adjacent cation and the chlorine atom of chloroform. The charge on the oxygen atoms (basic sites) was calcu lated using the electronegativity equivalence method. The CH stretchin g frequency of chloroform adsorbed on basic sites is well correlated w ith this oxygen charge.
