The Voigt profile of Mossbauer transmission spectra

Journal of Physics C: Solid State Physics, 1970
Mossbauer spectra, obtained with sources of 57Co in palladium and absorbers of sodium ferrocyanide, have been fitted to a Voigt profile by a procedure which enables the optimum values of the separate Lorentzian and Gaussian width components to be determined.

Transmission Spectra without Interference Fringes

Applied Spectroscopy, 1977
Rich colors decorating oil slicks on water are interference fringes. These fringes arise from the constructive and destructive interference of the multicomponents of light beams generated from partial reflection of the incident light beam at the first and second surfaces of a transparent sample having plane parallel surfaces. Fringes are reflection (or

The efficacy of sunscreening agents: protection factors and transmission spectra

Clinical and Experimental Dermatology, 1982
Summary Fifty-five sunscreening agents were tested for their protection factor (PF) against ultraviolet radiation (UVR) and for transmission between 280 and 600 run. The results are tabulated so that the less efficacious sunscreens, although suitable for protection against natural and artificial light in people with normal skin, may be separated ...

Comparison of Transmission and Internal Reflection Infrared Spectra of Cocaine

Journal of Forensic Sciences, 2001
Abstract Comparing the infrared transmission spectrum of cocaine HCl to its attenuated total reflection (ATR) spectrum has raised questions about the use of ATR spectra for forensic drug analysis. Whenever infrared spectra are collected using different modes or sample preparation methods, small variations in peak intensity ratios or peak

Spectra restoration of a transmissive periodic structure in near-field diffraction (Talbot spectra)

Journal of the Optical Society of America A, 2015
The free-space near-field diffraction of a transmissive periodic structure is studied with Fresnel-Kirchhoff diffraction formula. A new effect named Talbot spectra is proposed theoretically from the results, showing that under some conditions the spectra of an incident coherent polychromatic light can be completely restored after the diffraction.

The shape of transmission spectra of thin films deposited on a substrate

The Journal of Chemical Physics, 2004
On the basis of the previous considerations [E. G. Bortchagovsky and U. C. Fischer, J. Chem. Phys. 117, 5384 (2002)] we analyze here the shape of the spectral lines created in transmission spectra by thin films deposited on a substrate. We demonstrate that such lines have as a rule the shape of an asymmetrical Fano line with the minimum shifted from ...

Transmission spectra for one-dimensional potentials in the semiclassical approximation

Physical Review A, 1995
It is found that in the semiclassical approximation, in situations with no turning point on the real axis, the reflection of a particle in a one-dimensional scattering potential U(z) occurs at the pairs of complex-conjugate reflecting points that include, at least, turning points and simple poles of the function U(z).
