Abstract
A simple relationship between the normalized ion motion frequency in t he far infrared and the optical basicity was established for all alkal i berate glass systems, suggesting that far infrared spectroscopy can be used as a reliable technique for measuring optical basicity. Compar ison between basicity values obtained from far infrared frequencies an d those measured by ultraviolet spectroscopy, using Tl+ and Pb2+ probe ions electrolyzed into berate glasses, indicates that the mobile alka li ions occupy sites of high basicity.
