AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Infrared (IR) absorption spectroscopy and mass spectrometry have been simultaneously applied to dusty radiofrequency (RF) plasmas in methane, acetylene and ethylene. The combination of IR absorption spectroscopy and mass spectrometry allows the chemical co ...
In situ Fourier transform infrared absorption spectroscopy has been used to study the composition of particles formed and suspended in radio-frequency discharges of silane-oxygen-argon gas mixtures. The silane gas constumption was observed by infrared abso ...
Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) has been established as a good and relatively sensitive method for qualitative analysis of powders and rough surfaces. The technique is non-destructive and high quality spectra can be eas ...
Differential photoluminescence excitation (DPLE) spectroscopy is shown to be an efficient way to measure gain and absorption spectra of excited semiconductors. Very small excited volumes can be probed, and thus DPLE spectroscopy is ideal to probe nanostruc ...
Methods and app. to study biol. mols. or biol. components at or in self-assembled monolayers (SAMs) on metal surfaces such as gold in aq. environments using attenuated total internal reflection Fourier transform infra-red (ATR-FTIR) spectroscopy are descri ...

An adaptation of Kubelka's general model of diffuse reflectance and diffuse transmittance of light to nonideal scattering samples is proposed. It is applied to quant. Fourier transform IR spectrometry of nondiluted surface-derivatized silica powders. Corre ...
The capability to perform absorption spectroscopy with hard x-rays was added to the synchrotron imaging spectromicroscopy technique. We present several successful test cases. First, the EXAFS (extended x-ray absorption fine structure) analysis was implemen ...
Advances in chem. modification electrothermal at. absorption spectrometry (ETAAS) are reviewed with an emphasis on the progress made after the publication of the previous extensive review (Tsalev et al., Spectrochim. Acta Rev. 1990, 13, 225). Among the top ...
The abs. :CF2 concn. is measured in situ and in real time by UV-absorption spectroscopy in the IR multiphoton dissocn. of CF2HCl during and after the laser pulse. The :CF2 prodn. rate is measured as a function of the laser intensity and the temp. at 9.17 m ...
This work is devoted to an "old" defect and its annealing characteristics, namely the divacancy center in Si. IR spectroscopy is applied to study the annealing kinetics of divacancy-related absorption peaks in electron-irradiated Czochralski-grown sample ...
