Abstract : A study was made of the far infrared spectra at liquid helium temperatures. At low temperatures rotational modes of vibrations become librational. A spherical environment was produced by condensing water and hydrogen fluoride in rare gas matrices. Pure crystals of polyatomic molecules such as hydrogen sulfide and iodide were studied. Solid solutions of water and deuterium oxide in rare gases were studied. Marked improvements were accomplished in a far infrared detector which operates at 1.5 Kelvin and in the construction of a low temperature infrared cell. (Author)
