  2. Health and environmental impact of transport - Wikipedia

    en.wikipedia.org/wiki/Health_and_environmental...

    Health effects of transport include noise pollution and carbon monoxide emissions. While electric cars are being built to cut down CO 2 emission at the point of use, an approach that is becoming popular among cities worldwide is to prioritize public transport, bicycles, and pedestrian movement .

    Simulated vibration-rotation line spectrum of carbon monoxide, 12 C 16 O. The P-branch is to the left of the gap near 2140 cm −1, the R-branch on the right. [note 2] Schematic ro-vibrational energy level diagram for a linear molecule. Diatomic molecules with the general formula AB have one normal mode of vibration involving stretching of the ...

  5. Molecular vibration - Wikipedia

    en.wikipedia.org/wiki/Molecular_vibration

    A molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged. The typical vibrational frequencies range from less than 10 13 Hz to approximately 10 14 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm −1 and wavelengths of approximately 30 to 3 μm.

  6. Carbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide

    Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...

    English: Part of the rotational-vibrational spectrum of carbon monoxide (CO) gas (from FTIR), showing the presence of P (<2140 cm-1) and R (>2140 cm-1) branches. Frequency is on the x-axis, and absorbance on the y-axis.

    Furthermore, a vibration will be Raman active if there is a change in the polarizability of the molecule and if it has the same symmetry as one of the direct products of the x, y, z coordinates. To determine which modes are Raman active, the irreducible representation corresponding to xy, xz, yz, x 2 , y 2 , and z 2 are checked with the ...

  9. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    In carbon monoxide (CO, isoelectronic with dinitrogen) the oxygen 2s orbital is much lower in energy than the carbon 2s orbital and therefore the degree of mixing is low. The electron configuration 1σ 2 1σ* 2 2σ 2 2σ* 2 1π 4 3σ 2 is identical to that of nitrogen.
