What is IR spectroscopy?
Bonds in a molecule absorb infrared radiation at characteristic wavenumbers
What is radiation absorbance dependant on?
More polar bonds = stronger peaks Molecular vibration
Why is the fingerprinting region highly advantageous
Allows identification of a molecule by comparison of spectra
Fingerprint region range
1500 - 500
How does greenhouse gases heat up the earth?
Radition emitted by the sun which enters the atmosphere and bypasses greenhouses gases due to shorter wavelengths. Radition remitted by the Earth as longer wavelengths. Greenhouse gases can absorb these longer wavelengths. Heating up the atmosphere.
What property in greenhouse gases allow IR absorption?
Polar bonds
Is C=O bond in CO2 have the same wavelength number as normal C=O groups?
No
