Abstract:

Development was undertaken of Far-Infrared techniques at liquid helium temperatures to get absorption and reflection spectra from which are deduced the optical constants of the solids. They appear fruitfull and disclose 1 the supertransmission of crystals at low temperature in the far-infrared 2 the different behaviour of crystals and glasses 3 far infrared electronic transitions in several materials 4 a drastic change of damping and anharmonicity with temperature.
