A careful analysis of the imaginary dielectric index ($\epsilon$) spectra has provided important insights into the question of electrical and mechanical anharmonicity in the lattice modes of LiF. To further investigate this problem, work has been done on the IR transmission spectra of LiF thin films at high pressures. The optical indices as a function of pressure have been obtained through a Kramers-Kronig transmission dispersion analysis of the transmission values. Results will be presented and evaluated in terms of various models of anharmonicity. The proper methodology to obtain reliable high pressure IR transmission data of LiF thin films will also be outlined. en_US dc.format.extent 141098 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE INFRARED OPTICAL PROPERTIES OF LiF AS A FUNCTION OF TEMPERATURE AND PRESSURE en_US dc.type article en_US
