Admittance bridge measurements in the frequency range 0.1-106 Hz have been combined with Fourier transform interferometric spectral measurements in the range 1012-1013 to yield major portions of the complete a.c. field response function for some highly conducting lithium fluoroborate and sulfoborate glasses. Interpretation of these results has been assisted by studies of the detailed dynamics of ion motion revealed by ion dynamics computer simulation studies of high fictive temperature lithium and sodium silicate glasses, and of some unphysical glasses with (a) massive, slowly vibrating "oxygen ions", and (b) light Na+ ions of the same mass as the Li ions.
