More information on the manner in which spectra in this collection were collected can be found here. Notice: Concentration information is not available for this spectrum and, therefore, molar absorptivity values cannot be derived.

The CO 2 molecule shows a rich infrared spectrum of which we have discussed an important part here. The spectrum shows us the properties of the molecule and the effects quantum physics has on it. If you are interested in measuring the concentration of carbon dioxide in beverages, Anton Paar’s CarboQC and CboxQC are perfectly suited.

This is an IR spectrum of CO 2 corresponding to the vibrations below. Clicking on a peak will take you to corresponding vibration. These vibrations are the result of a C++ program. For an explanation of how it works, click here.

The complete infrared spectrum of C may consistently be explained in terms of a linear symmetrical model, making use of the selection rules developed by Dennison and the resonance interaction introduced by Fermi. The inactive fundamental appears only in combination bands, but at 15μ and at 4.3μ absorb intensely.

Infrared spectrum of Carbon Dioxide (CO2) with animations of vibrational modes, demonstrates why this molecule behaves as a greenhouse gas and introduces IR spectroscopy.

Highly Sensitive Absorption Spectroscopy of Carbon Dioxide by ICLAS-VeCSEL Between 8800 and 9530 cm -1; Y. Ding, A. Campargue, E. Bertseva, S. Tashkun, and V.I. Perevalov; J.Mol.Spec. 231:117-123 (2005).

Calculated vibrational frequencies for CO 2 (Carbon dioxide). Gas-phase IR spectra can be found in the NIST Chemistry Webbook here.

A review is made of the experimental data which determine the positions of the carbon dioxide vibrational energy levels. These include the results of a recent investigation of absorption bands appearing in the spectrum of Venus, as well as new and as …

OCS is isoelectronic with CO2 and both involve carbon doubly bonded to two group 16 elements. The full IR spectrum of OCS is shown overleaf. The fundamentals corresponding ν1, ν2 and ν3 have been labelled and are at 2062, 520 cm-1 and 859 cm-1 respectively. Impurities: CS2 (1530 cm-1) CO2 (2350 cm-1) Mark these on the spectrum!
