Review of Literature and Presentation of the Problemdely differing problems and are often of a random nature. Data relating to the second-order infrared spectral lines of molecules which we have studied will be included in the appropriate sections of this treatment.

Appearance of the Rotational Oscillations of Ethyl and Heavier Groups in the Low-Frequency Raman SpeIn addition to the rotational oscillations of the methyl groups, we were also interested in the appearance of the rotational oscillations of ethyl and heavier groups in the low-frequency Raman spectra. From this point of view the most convenient class of substances was that comprising the methyl-substituted butanes (CH.-CH.-CH.-CH.).

Theoretical Study of the Optical Properties of MetalsIt is well known that the optical properties of metals may be described by a complex refractive index n′ = n - iϰ or surface impedance Z [12, 44]. The relation between the quantities and the microscopic characteristics of the metals is given by the skin-effect theory.

Measuring Method. are spherical mirrors; P and A are the polarizing elements. The first of these is usually called the polarizer, and the second the analyzer. Between these are the samples L. The exit slit S. lies at the focus of objective O. (in particular cases there may be a light receiver in place of slit S.).

Prophylaxis

Experimental Methodo measure isolated lines with an intensity of the order of 0.5 units in the scale of [18] (where the intensity at the maximum of the 802 cm. line of cyclohexane is taken as 250).* We note that even this intensity is not the limiting one, since, in a number of practical cases the background had no interfering effect on the measurements.

Results of the Measurements and 4.2°K. The temperature dependence of n is considerable over the whole spectral range; the temperature dependence of ϰ is only large in the range λ = 8–12 μ. In the range λ = 2–5 μ, ϰ varies only slightly with temperature.
