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 ...
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 ...
The absorbance signal in electrothermal at. absorption spectrometry is a result of the processes of atom formation and dissipation and 1st of all depends on the initial generation of atoms from the surface. The rising part of the absorbance time profiles c ...
The temp. jump relaxation method was used for kinetic measurements in the gas phase. The system N2O4 .dblarw. 2NO2 was studied. Fast temp. jumps were induced by IR absorption from a CO2 laser. Temp. jumps of
In situ Fourier transform infrared (FTIR) absorption spectroscopy has been used to determine the fractional depletion of silane in a radio-frequency (ri) glow discharge. The technique used a simple single-pass arrangement and was implemented in a large-are ...
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 ...
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 ...
The equil. I2(g) + 2NO(g) = 2INO(g) was studied at room temp. by UV absorption spectroscopy. The equil. const. was measured as kp = (2.7 +- 0.3) * 10-6 atm-1 at 298 K. The 3rd-law calcns. lead to DHf(INO) of 120.0 +- 0.3 kJ/mol. The relative absorption spe ...
We present a far infrared gas spectrometer which uses a thin film pyroelectric detector integrated on silicon. The detector is in-house fabricated and consists of 1 x 50 elements of sol-gel deposited, zirconium rich lead titanate (PZT) which are suspended ...
The stabilizing role of permanent Ir modifier deposited on W-treated (WTP) and Zr-treated (ZrTP) platforms of transversely heated graphite atomizer (THGA) was studied in detail by electrothermal at. absorption spectrometry (ETAAS) and different surface tec ...
