How does infrared spectroscopy identify organic compounds?
Infrared spectroscopy identifies organic compounds by measuring the absorption of infrared radiation by the compound's functional groups. Each functional group absorbs infrared radiation at specific frequencies, which produce characteristic peaks in the IR spectrum. By comparing these peaks to reference spectra, the functional groups present in the compound can be identified.
Infrared spectroscopy analysis of unknown compounds?
Infrared spectroscopy is a powerful technique used to identify functional groups in unknown compounds by measuring the absorption of infrared light. By comparing the peaks in the infrared spectrum of an unknown compound to reference spectra, the functional groups present can be identified. This information can help in determining the molecular structure and composition of the compound.
How ir spectrum compound recorded?
An IR spectrum of a compound is recorded by passing infrared radiation through a sample of the compound and measuring the absorption of different wavelengths by the sample. The resulting spectrum displays peaks and troughs corresponding to different functional groups present in the compound, which provides information about its structure and composition.

What does infrared radiation tell us about molecules?
It tells us about how bonds stretch (or how atoms vibrate). This tells us about bond strengths and bond lengths, and can also be used to identify molecules (the infrared spectrum can be used as a "fingerprint" to identify what kinds of bonds a particular molecule has in it.
What information can be obtained from the infrared spectra of vanillin?
The infrared spectra of vanillin can provide information about the functional groups present in the molecule, such as the presence of carbonyl groups, hydroxyl groups, and aromatic rings. This data can be used to identify and characterize the compound.
What types of light cannot be seen?
Ultraviolet light, infrared light, and X-rays are types of light that cannot be seen by the human eye. While these forms of light are present in the electromagnetic spectrum, they are outside the visible spectrum for humans.
