摘要：

Based on the influence of the composition (Si/Al and Si/Ga ratio) on the framework vibrations of zeolites with different structure types (FAU, LTL, BETA, MOR, MEL, MFI, TON, and MTW), an electronegativity value for gallium substituted into zeolite frameworks is proposed (Sanderson electronegativity scale). The present electronegativity value agrees with the known physicochemical properties of gallium substituted zeolites. © 1991.
