This study analyses the glow discharge of He and N2 mixture at pressure 2.0 Torr, power 10 W, flow rate 16.5 l/min, by using optical emission spectroscopy mass spectrometry. The bands were measured in wavelength range 200–1100 nm. principal species observed N2+ (B2Σ+u→X2Σ+g), (C3Πu→B3Πg), He, which are good agreement with results Besides, electron temperature ion density determined a double Langmuir probe. Results indicate that is 1.55–2.93 eV, concentration order 1010 cm−3. experimental for...
DC generated Ar–CO2 discharge for plasma mixtures at 2.0 Torr is investigated to evaluate the variation in electron temperature and density, energy distribution function, population densities of reactive atomic, molecular, ionic species CO2–Ar plasmas as a function Ar percentage mixtures. Optical emission spectroscopy quadrupole mass spectrometry are used determine mode percentage. The observed were CO2, O2, CO, O, C2, Ar, which agree very well with observation. In addition, single Langmuir...
Optical emission spectroscopy was applied for plasma characterization during erosion of substrates asphaltene. The amount 100 mg asphaltene carefully to an electrode and exposed air glow discharge at a pressure 1.0 Torr. generated in stainless steel chamber by AC generator with frequency 60 Hz output power about W. electron temperature found be 6.88 eV, the ion density is 3.5 × 1016 cm−3. As plasma, surface etched. from molecular bands CS2, O3, N2+, NO, O2, CS, S2, CN, C7H7, C2, H2, C2−,...
The FTIR spectrum of CH2ClF (natural isotopic mixture) was investigated in the ν4, ν9 and ν5+ν6 band region between 950 1160 cm−1 at resolution 0.004 cm−1. ν4 vibrations A′ symmetry give rise to a/b hybrid bands with a predominant a-type component. vibration A″ symmetry, expected c-type contour, shows an intense Coriolis-induced parallel component (ΔKa = 0, ΔKc 0) derived from mixing v4 1 vibrational state. high-resolution spectra have been analyzed for first time, while assignments band,...
The infrared spectrum of a sample containing 13C mono-substituted isotopologues acetylene, H12C13CH, H12C13CD, D12C13CH and D12C13CD has been recorded in the 6130−6800 cm− 1 region using femto-Fourier transform-cavity enhanced absorption spectroscopy (femto-FT-CEAS) apparatus. Three bands for both H12C13CD were observed analysed, namely 2ν1 − GS associated hot from ν4 ν5. assignment overtone already reported literature [J.L. Hardwick, Z.T. Martin, M.J. Pilkenton, E.N.

Context. Diacetylene, C4H2, has been identified in several astronomical environments through its infrared spectrum. In contrast, monodeuterated diacetylene (DC4H) not detected space so far owing to the low isotopic abundance of deuterated species but also rather poor laboratory spectroscopic characterisation this molecule.
