INFRARED EMISSION SPECTROSCOPY OF HOT CARBON MONOXIDE

dominated by carbon monoxide and methane, the principle reservoirs of carbon on these planets. The relative CO and CH 4 abundances inform us about temperature and pressure conditions and also about mixing by global winds driven by intense but asymmetric heating for these tidally locked bodies. Emission spectra collected during secondary eclipses, as the hot Jupiter passes behind its parent ...

FTIR spectroscopy of hydrogen, carbon monoxide, and ...

· Adsorption of dihydrogen, carbon monoxide and methane, and co-adsorption of H 2 /CO, H 2 /CH 4 and CO/CH 4 on zinc oxide was studied by means of Fourier transform infrared spectroscopy. Besides the already known dissociation of dihydrogen and molecular adsorption of CO, methane was found to be adsorbed molecularly on coordinatively unsaturated Zn 2+ ions.

Infrared Spectroscopy: Theory

In IR spectroscopy, an organic molecule is exposed to infrared radiation. When the radiant energy matches the energy of a specific molecular vibra-tion, absorption occurs. A typical IR spectrum is shown below. The wavenumber, plotted on the X-axis, is proportional to energy; therefore, the highest energy vibra-tions are on the left. The percent transmittance (%T) is plotted on the Y-axis. An ...

· Carbon monoxide produced a single band at 1725 cm-1 for adsorption temperatures between 30 and 75. Above 75 this band could no longer be observed. When either COa or N20 was present in the cell the spectrum exhibited two or more in- verted bands. These were located at 2350 and 670 cm-1 for COz and at 2220, 1290, and 590 cm-1 for NzO. The significance of these bands and their influence on the in- terpretation of the spectra …

IR Spectroscopic Methods for the Investigation of the CO ...

Carbon monoxide (CO) is a toxic gas for mammals, and despite this fact, it is naturally produced in these organisms and has been proven to be beneficial in medical treatments, too. Therefore, CO-releasing molecules (CORMs) are intensively developed to administer and dose CO for physiological applications. Nearly all of these compounds are metal carbonyl complexes, which have been …

VIBRATION-ROTATION SPECTRUM OF CO - Rice University

In the present exercise we will be concerned with the spectrum of carbon monoxide, particularly in the infrared region. We will argue that the observed groups of lines can be understood as transitions between vibration-rotation levels of the molecule. Careful measurement of the transition frequencies will let us deduce the interatomic spacing and some characteristics of the interatomic ...

The interaction of carbon monoxide and dioxygen with low-temperature (T= 77 K) sublimates of cobalt(II) meso-tetraphenylporphyrinate (CoTPP) is studied by IR spectroscopy using isotopically labeled compounds (13 CO and 18 O 2).The obtained data confirm the coordination of CO and O 2 with the formation of axial complexes CoTPP · L (L = O 2, CO) and the mixed complex O 2 · CoTPP · CO.

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
