Optical constants of polyacetylene
Synthetic Metals, 1985Abstract Optical constants of neat cis - and trans -(CH) x and (CD) x films are determined by measuring infrared, visible and ultraviolet spectra of the film and its thickness directly. The absorption coefficient of cis -(CH) x at the absorption maximum 18 500 cm −1 was (1.5 ± 0.1) × 10 5 cm −1 and that of trans -(CH) x at 15 500 ...

In the UV—VIS spectral range the interaction of electric field with a liquid phase is important and the interaction of magnetic field with liquid can usually be neglected in most cases of practical optical metrology. The electric charges of molecules in liquids experience the coulombian interaction.

Optical Constants of Aluminium
Proceedings of the Physical Society, 1960The optical constants of aluminium from the near ultra-violet (2500A) to the near infra-red (5μ) can be described, at least qualitatively, in terms of the Drude formula by the two parameters N and τ, the density of free electrons and the relaxation time, respectively.

The refractive index and extinction coefficient of purple K3Sb film prepared on a quartz substrate were determined from the transmittance data in the photon-energy region 0.5–6.2 eV through the Kramers–Kronig (KK) dispersion analysis. The interference effect due to the internal reflection of the light in the substrate was eliminated by taking the ...

The most apparent properties of metals, their luster and their color, have been known to mankind since metals were known. Because of these properties, metals were already used in ancient times for mirrors and jewelry. The color was utilized 4000 years ago by the ancient Chinese as a guide to determine the composition of the melt of copper alloys: the ...

Publisher Summary The optical behavior of a material is completely determined if its optical constants are known. Most of the work so far has been directed towards determining the major features in the optical spectra of the various compounds. Values of the optical constants have in most cases been only a by-product of these investigations and cannot

Physical Review, 1961
The optical constants for electrolytically polished silver samples were determined from normal-incidence reflectance data in the spectral region 2 to 10 ev. The sharp minimum in the curve for $k$ near 3.8 ev, which is associated with the onset of interband transitions, is deeper than in previous results. A second minimum is observed near 9.2 ev.
