A new electronic transition of PtS with a red degraded band head at 12 460 cm-1 was recorded and analyzed. Gas phase PtS was produced in a platinum-lined hollow cathode with a trace of SF6 gas, and the spectrum was recorded at near Doppler resolution using intracavity laser absorption spectroscopy. Molecular constants for the newly ...

We present the hygroscopicity of polymer and copolymer materials in the low terahertz (THz) frequency range using a linear absorption model. We identify COC 6013 and COC 5013 as optimal THz window materials, possessing both low hygroscopicity and high transmission in the THz regime. The correct choice of window material is of significance for transmission ...

Sputter deposited non-stoichiometric tantalum nitride films are oxidized in air between 200 and 500{degrees}C to form a passive film. The oxidized films have been studied with x-ray absorption near edge spectroscopy (XANES) and extended x-ray absorption near edge spectroscopy (EXAFS). Films exposed to KOH formed a ...

We describe a new type of spectroscopy based on picosecond transient strain in absorption photomodulation that can be used to detect and identify both allowed and forbidden optical transitions in solid thin films. We have applied the new spectroscopy to a variety of conducting polymer films such as polythiophene, ...

We have found that a strain-induced oscillation in the decay of the picosecond photoinduced absorption of polyacetylene (CH)(sub x) can be used to identify the allowed and forbidden electronic transitions in that polymer.
A first attempt at measuring the species evolution in the opaque post-detonation combustion product environment of a fuel-rich explosive using time-resolved absorption spectroscopy is presented. The time-resolved concentration of these species is helpful in identifying the rate and location of the extra energy released in the ...

Hydrophobic sites on the surface of protein molecules are thought to have important functional roles. The identification of such sites can provide information about the function and mode of interaction with other cellular components. While the fluorescence enhancement of polarity-sensitive dyes has been useful in identifying hydrophobic sites on a number of targets, strong ...
