Abstract

Infrared reflectivity measurements have been made on samples of cubic Cd

F_{2}

and Pb

F_{2}

between 10 and 150 μ at room temperature. The data have been analyzed by the use of reflectivity dispersion relations to obtain infrared dielectric properties of these substances as well as their optic-mode frequencies (transverse and longitudinal, TO and LO). For Cd

F_{2}

we find

ω_{TO} = 202

{cm}^{- 1}

;

ω_{LO} = 384

{cm}^{- 1}

;

ε_{s} = 8.09

. For Pb

F_{2}

ω_{TO} = 102

{cm}^{- 1}

;

ω_{LO} = 337

{cm}^{- 1}

;

ε_{s} = 27.4
